History Main / InterserviceRivalry

* ''Series/{{CSI}}''
** A friendly version has the LVPD playing another group in a baseball game.
** A bigger one is some of the police vs. the crime lab. Sophia wasn't happy about being assigned to the lab, and neither was Brass initially.
* ''Series/{{CSINY}}'':
** NYPD vs FDNY. One episode had a hockey game between the two. As expected, a brawl ensues.
*** Averted by Mac and his FDNY buddy, who have a standing bet on the outcome of the matches. Loser buys the winner dinner. In the season 9 opener, Mac tells his friend he's tired of losing...5 in a row at that point.
** Internally, the pure detectives tend to look down on Mac's team, seeing them as nerds/geeks. Danny notices this when he becomes a sergeant for a few episodes.

In ''Fanfic/CodeGeassLelouchOfBritannia'', Lelouch gains some favors from the Army high command by using his tactical genius to allow the underdog cadets to defeat the midshipmen at the Army-Navy football game.

* Santa Barbara Police Department vs. Coast Guard in ''Series/{{Psych}}''. [[DaChief Chief Vick's]] sister was the leader of the Coast Guard.
* Constantly averted in ''Series/TheWire''. The broke and understaffed Baltimore City police would love nothing more than the FBI taking over a case or two. Unfortunately, the FBI's superiors are only concerned with terrorism investigations, rather than the drugs and crimes that plague Baltimore -- although a certain degree of under the table assistance is rendered by sympathetic FBI agents.
* Franchise/StargateVerse:
** In ''Series/StargateSG1'' and ''Series/StargateAtlantis'', Air Force characters have made several references to an ongoing rivalry with their Marine coworkers (and, less frequently, their scientist coworkers).
** There's also a constant rivalry with the N.I.D about who gets what piece of alien technology.
** For the most part, though, interservice rivalry is implausibly averted. The USAF's technical expertise seems only exceeded by its success in defending its budget. Even though each service would have compelling arguments for an equal or superior share of a joint command, the Army (U.S. Army Special Forces, most missions call for infantry more than anything) and Navy (expertise running large vessels called "ships," the USMC, Navy [=SEALs=]) departments evidently are happy to let the Air Force run the show. The fact that the SGC is still not a joint command after 10+ years is one of the greatest triumphs in the history of Pentagon politics.
** In another implausible aversion, the Air Force operates a SpaceNavy, for the most part using [[SpaceIsAnOcean typical Space Navy terminology]]. Arguably, the RealLife Air Force would more likely classify "starships" as aircraft which just ''happen'' to be very, very large. Use of Navy terminology simply poses the unwanted question of why the Navy isn't more heavily involved.
** In ''Film/StargateContinuum'', Carter and Mitchell both make faces when Landry implies that if their universe gets a Stargate program, it will be run by the Navy.
** Occasionally a bit of RealLife Interservice Rivalry pops up with regard to plot developments that are often nixed in BackedByThePentagon productions. For example, the plot of the film ''Film/TheSumOfAllFears'' was altered to have terrorists merely severely damage a U.S. aircraft carrier, as opposed to sinking/destroying it outright. In one SG-1 episode, the Goa'uld destroy an entire U.S. Navy carrier battle group... which the ''Department of the Air Force'' technical advisors evidently had no problem with! FWIW, "destroyed by Aliens" may be less a problem for the military in general, than "destroyed by the Russians".
* Nearly any PoliceProcedural featuring repeated visits from InternalAffairs. These include, but are not limited to the various ''Series/CSIVerse'' shows, the various ''Franchise/LawAndOrder'' shows and ''Series/{{Monk}}''.

* Sometimes MI 5 vs. MI 6 in ''Series/{{Spooks}}'', sometimes it's JurisdictionFriction.
* This flares up from time to time between the various branches of the government's federal agencies in ''Series/TwentyFour''.
* Played for laughs between the Home Guard and the ARP Wardens in ''Series/DadsArmy''.

* "I'm so sick of Congress right now that I could vomit." (a recurrent feeling for the characters from ''Series/TheWestWing'')
** From Leo: "A first-time Congressman was excited for his first vote, saying 'Where are the Republicans? I want to meet the enemy'. An older, more experienced Representative replies 'No no no, the Republicans are the opposition. The Senate's the enemy"
* In the ''Series/HomeImprovement'' episode "'Twas the Night Before Chaos", Tim tries to get his father-in-law, who happens to be an army vet, to help him put up his Christmas display to beat his long-time rival, an eighty-something retired proctologist. He doesn't want to get involved in their rivalry until Tim mentions that the man was in the navy. Then he's only too eager to beat "that navy butt doctor."
* ''Series/{{MASH}}'':
** A hilarious episode has the doctors endure an unexploded aerial bomb dropped ''from [[FriendlyFireIndex their own side]]'' in the middle of the camp, and to defuse it they have to find out which branch of the military uses that kind of explosive. It doesn't help that this is all taking place during the Army vs. Navy football game that everyone's following. [[spoiler:The bomb actually belongs to the [=CIA=]... - and it's filled with propaganda leaflets signed by UsefulNotes/DouglasMacArthur urging their recipients to surrender.]]
** The 10th season episode ''[[Recap/MashS10E19SonsAndBowlers Sons and Bowlers]]'' also features this as the 4077th tries to beat a local Marine unit in a friendly game of bowling after losing several times to that same unit in other friendly sporting events. However, when wounded pour in the interservice rivalry is dropped in a heartbeat as the Marines render aid to the 4077th and the wounded.
* The rivalry between two of the branches of the High Guard in ''Series/{{Andromeda}}'' is a textbook example. The Argosy (fleet officers) dislike the Lancer Corps (ground troops), calling them "rock hoppers". The Lancers reciprocate with "Aggros" for fleet officers. Even the [=AIs=] participate in the rivalry, when [[SpaceshipGirl Rommie]] insults a Lancer troop transport.
* Most of the times the FBI is involved an episode of ''Series/LawAndOrder'', it's in a "them vs. us" role, though on occasion, they work together. On the law side, the ADA finds its federal equivalent more often working against him/her than with her/him.
* Played for laughs in one episode of ''Series/TheUnit''. Part of Bob Brown's initiation into the Unit, an Army black ops squad, involved picking a [[BarBrawl bar fight]] with some Navy guys on shore leave.
* The ''Series/{{Vegas|2012}}'' episode "Exposure" has a couple moments of ribbing between Sheriff Lamb, a former Army MP, and the Air Force investigator assigned to his Case of the Week.
* ''Series/{{CSI}}''
** A friendly version has the LVPD playing another group in a baseball game.
** A bigger one is some of the police vs. the crime lab. Sophia wasn't happy about being assigned to the lab, and neither was Brass initially.
* ''Series/{{CSINY}}'':
** NYPD vs FDNY. One episode had a hockey game between the two. As expected, a brawl ensues.
*** Averted by Mac and his FDNY buddy, who have a standing bet on the outcome of the matches. Loser buys the winner dinner. In the season 9 opener, Mac tells his friend he's tired of losing...5 in a row at that point.
** Internally, the pure detectives tend to look down on Mac's team, seeing them as nerds/geeks. Danny notices this when he becomes a sergeant for a few episodes.
* ''Franchise/StarTrek'':
** Referenced in the ''Series/StarTrekTheOriginalSeries'' episode "[[Recap/StarTrekS1E19TomorrowIsYesterday Tomorrow is Yesterday]]". When USAF Captain (O-3) Christopher is accidentally transported onto the ''Enterprise'', he asks Captain (O-6) Kirk if the Navy ran the ship. Kirk answers that they are a "combined service". ([[WordOfGod Off-camera]], Creator/GeneRoddenberry {{insiste|ntTerminology}}d that Starfleet [[TakeAThirdOption was most similar to the Coast Guard]].)
** ''Series/StarTrekEnterprise'':
*** Earth Cargo Service against the early Starfleet. In the episode "[[Recap/StarTrekEnterpriseS02E020Horizon Horizon]]", Ensign Travis Mayweather is berated by his brother about how recruits would rather join Starfleet than ECS.
*** Deconstructed in the later episode "[[Recap/StarTrekEnterpriseS03E15Harbinger Harbringer]]". There's some rivalry between [[SpaceMarine Military Assault Command Operations (MACO)]] officer Major Hayes and Starfleet Lieutenant Malcolm Reed, implying tension between the two organizations. Things escalate into a fistfight... which [[SurprisinglyRealisticOutcome leads to Captain Archer]] [[WhatTheHellHero thoroughly chewing both of them out]].
** ''Series/StarTrekTheNextGeneration'': In the episode "[[Recap/StarTrekTheNextGenerationS6E13FaceOfTheEnemy Face of the Enemy]]", it's revealed that there is little love lost between the regular Romulan military and [[StateSec the Tal'Shiar]], with members of the former believing that the latter would cause the death of the entire Empire. (This later played out as the Tal'Shiar sabotaged the Federation efforts to evacuate Romulus before the Romulan sun went supernova.)
** ''Series/StarTrekDeepSpaceNine'':
*** Early on, there's a bit of a rivalry between Starfleet and the Bajoran Militia, with Major Kira in particular not liking having to work for Commander Sisko. They warm up to each other. The use of Army ranks for the Militia doesn't hurt the allusion.
*** Odo, also an officer of the Militia (based on his uniform if nothing else), has his own way of doing things and very much dislikes it when Starfleet tries to insert itself in his work, whether by actively interfering or forcing him to work according to their legal code. He even tries to resign at the beginning of season three when a lieutenant commander from Starfleet Security is assigned to the station, and humiliates Worf for wrecking an undercover operation after the latter was repeatedly told to leave it alone (Worf was chief of security in his last post, but is now part of the station's strategic planning staff).
*** Among Cardassians, Central Command and the Obsidian Order, the one being regular military, the other being the SecretPolice used to keep tabs on the military (and vice versa, as the Obsidian Order is not allowed to have military forces). This is a source of some of the friction between Dukat and Garak.
*** Within the Dominion, there was some tension between the Vorta and the Jem'Hadar. Vorta often looked at the Jem'Hadar as easily replaceable cannon fodder and at times would throw them under the bus to save their own skins. Meanwhile the Jem'Hadar saw the Vorta as duplicitious, scheming, and cowardly. The only thing that kept the two races working together was their genetically engineered absolute loyalty to the Founders.
*** Another episode focused on the rivalry between veteran Jem'Hadar created in the Gamma Quadrant, and newer Jem'Hadar created in the Alpha Quadrant after the Dominion's access to the wormhole was cut off. Captain Sisko takes full advantage of this and plays both sides against each as he attempts to regain control of the ''Defiant''. This particular case, however, wasn't explored again after this episode (there were plans, but they were scrapped in favor of more focus on the TeethClenchedTeamwork between the Cardassians and the Dominion).
** ''Series/StarTrekVoyager'' set one up internal to ''Voyager'' by combining the remnants of a Starfleet crew with the remnants of a Maquis[[note]]A [[YourTerroristsAreOurFreedomFighters militia/terrorist organization]] from the Federation-Cardassian border seeking independence from ''both'' governments.[[/note]] crew they had been sent to capture. This was meant to create tension between the characters [[AbortedArc but was mostly ignored aside from a few first-season episodes]].
* Based as it was in RealLife, the way the SS and regular German forces looked at each other in ''Series/HogansHeroes''. When SS personnel or units suffered some misfortune, Klink was never heartbroken.
* ''Series/BabylonFive'':
** The GROPOS (Marines) and Navy types seem to have a mutual disdain for each other, though this isn't seen much as the station is run by [=EarthForce=] navy. The station's fighter squadrons also seem to enjoy good-natured (mostly) ribbing of each other.
** In the season 5 DistantFinale "[[Recap/BabylonFiveS05E22SleepingInLight Sleeping in Light]]", an [=EarthForce=] officer indicates disdain for the Rangers, the paramilitary group that acts as the Interstellar Alliance's elite forces.
* ''Series/TheMusketeers'' and the Red Guard loathe each other and would love nothing more than to see the other humiliated. It doesn't help that their leaders Treville and Cardinal Richelieu consistently clash with each other.
* ''Series/GoodNewsWeek'': Invoked by Paul [=McDermott=] when [[UsefulNotes/AustralianPolitics John Howard's]] government was considering sending in the army to deal with a docks dispute:
--> "No, no, no. You send the ''navy'' in to deal with a dock strike. You send the army to deal with a coal miners' strike, and you send the air force in to deal with a pilots' strike. Otherwise, the navy, army, and air force get into a big demarcation dispute and go out on strike, and the government has to send in the wharfies to defend us against invasion! Which isn't a bad idea. When those wharfies cover the coastline, '''nothing''' gets ashore!
* Played for laughs with the Parks Department/Library Services enmity on ''Series/ParksAndRecreation''. The fact that ex-spouses Ron and Tammy 2 are the respective heads probably has an effect.
* ''Series/AgentsOfSHIELD'':
** At the beginning of the second season, Brigadier General Glenn Talbot, US Air Force, is rather upset to learn that his son said he wanted to join the Navy when he grew up. On a more serious note, a sizable part of that season features Director Coulson trying to resolve the rivalries and outright hostilities between SHIELD and just about everyone else in the post-''Film/CaptainAmericaTheWinterSoldier'' world.
** For the first part of season 3, SHIELD also finds itself in conflict with the ATCU, a new organization put together to deal with the widespread outbreak of new Inhumans. Coulson eventually puts together a working compromise between the two groups, saying that he's [[LampshadeHanging tired of fighting people they should be working with.]]
* ''Series/ColdCase'': Turns up in the episode "Shore Leave". A marine bound for the Korean War was murdered while on furlough in Philadelphia. He was known to have rubbed several sailors up the wrong and beaten the navy champion in a shipboard boxing match, so the cold case team wonders if his murder could have been a case of interservice rivalry getting out of hand, especially after they learn he ventured into a navy bar. However, a flashback reveals that the sailors did resent his presence there and would have beaten him up, only he was threatened by a civilian, which caused all of the sailors to rally behind him.
* ''Series/That70sShow'':
** "Jackie Bags Hyde" has Red, a navy veteran who served in combat during World War II and the Korean War, miffed that Bob, who was a member of the National Guard and never saw combat, is allowed to march in the Veterans Day parade.
** In "Backstage Pass", [[RashomonStyle Red and Kitty are arguing about how they first met]]. In Red's version, he saw a Marine try to have his way with her, so when Red stepped in, the Marine derisively called him "Bell-bottom" while Red called him "Leatherneck" before [[TalkToTheFist punching him out]].
* You name it and Danny Reagan has probably fought with it on ''Series/BlueBloods''; FBI, US Marshals, his local District Attorney investigators. Also, as with several stories focusing on the NYPD, there is a butting of heads between the PD and the Fire Department that crops up occasionally.
* ''Series/ThePacific'': The Marines on Guadalcanal aren't pleased when the Army arrives to reinforce them. Almost immediately, a small prank war breaks out between the two branches when an Army truck nearly runs over a group of Marines for no reason and the Marines respond by stealing supplies from the Army camp during an Air raid. (The Army doesn't know that Japanese planes only attack the airfield, so they run and duck for cover thinking they're about to attack the beaches where they've landed)
* The various departments behind the scenes in ''{{Series/Westworld}}'' squabble with and belittle each other constantly. Behavior, Quality Assurance, Narrative, and Livestock Management are all mentioned. Manufacturing is possibly referenced as "the body shop", but that could be the repair guys in LM too.
* ''Series/HoratioHornblower'', "The Frogs and the Lobsters": The Royal Navy and British Army barely tolerate each other, but neither of them gets along well with the French royalists. They are assigned to a joint mission in France and are supposed to fight against the French Revolutionaries.
* Downplayed forms of this pop up occasionally on ''Series/BurnNotice'':
** [[TheLancer Sam]] is a retired [[UsefulNotes/NavySeals Navy SEAL]], (Navy special operations, generally regarded as one of the most elite units in the U.S. military) and while he has friends from every branch of the military and intelligence services and shows respect to them, he also has a tendency to good-naturedly tease all of these other groups. For example, in the first episode he teases his longtime friend and [[UsefulNotes/{{CIA}} CIA agent]] Michael by calling spies "a bunch of bitchy little girls", and a couple of seasons later when the [[UsefulNotes/CoastGuard U.S. Coast Guard]] is mentioned Sam jokingly refers to it as "the Navy's little sister." One of the very few times Sam ever lost his cool with a VillainOfTheWeek is when the guy put together that Sam was ex-military and mockingly guessed that Sam was in the Coast Guard, which infuriated Sam so much he briefly lost concentration and the guy then got the better of Sam in a short bit of hand to hand combat.
--->'''Milovan:''' What were you, before you became a rich man's errand boy? A cop? ''[Later]'' I was wrong. You are an ex-military. Washed up, soft now, but I see. ''[Laughs derisively]'' What were you, a [[ButtMonkey Coast Guard]]?\\
'''Sam:''' ''[Gets in Milovan's face, genuinely furious]'' Try Navy SEAL, pal.
** A criminal version occurs when Fiona points out that there's a very big divide among smugglers when it comes to [[ArmsDealer gun smugglers]] versus [[HumanTraffickers people smugglers]]: the two groups don't like each other much.
* In ''Series/TheExpanse'', Bobbie Draper was a Martian SpaceMarine and Cotyar a member of Earth's Military Intelligence. When the two [[TeethClenchedTeamwork are forced to work as a team]], one of the first things they do is share some choice insults about each other's past military experience.
-->'''Bobbie:''' ''[After seeing Cotyar expertly handle a gun]'' You served?\\
'''Cotyar:''' [=SIGINT=], back in the day.\\
'''Bobbie:''' ''[voice dripping with disdain]'' Ah, Military "Intelligence".\\
'''Cotyar:''' Yeah, my IQ tested too high to be [[DumbMuscle a Marine]].\\
'''Bobbie:''' And [[SpiesAreDespicable your morals tested low enough to be a spy]].
* Comes up repeatedly on ''Series/{{Bones}}'', particularly the Army-Navy version.[[note]]Seeley Booth was an Army sniper, his brother Jared was in the Navy.[[/note]]
-->'''Booth''': How could a guy with military training miss with a scattergun? What were you, Navy?
* ''Series/GrowingPains'': The Seaver kids' paternal grandfather is an ex-MP and their maternal grandmother's boyfriend is ex-Army. The two only take about ten seconds to smugly insult each other's branch of the military during their first meeting.
* A villainous version comes from ''Series/ChoujinkiMetalder'', where [[BigBad God Neros]] has four different divisions of his army, not all of whom get along with each other (oftentimes there are promotions from the fighting between two different warriors) or follow the same goals; Neros is forced to realize this when Topgunder takes off on his own. (''Series/VRTroopers'' downplayed this, though General Ivar and Colonel Icebot -- both of whom came from ''Series/JikuuSenshiSpielban'' --would frequently bicker with each other over plans and the like.)
* Largely subverted on ''Series/{{Obliterated}}'', as the team is made up of members of the CIA (Ava), NSA (Maya), and all four branches of the Armed Forces ([=McKnight=] and Trunk are Navy [=SEALs=], Gomez is a Marine Corps sniper, Yung is an Air Force helicopter pilot and Hagerty is an Army EOD Specialist). The team generally works well together, but they all hate the FBI, and the feeling is mutual.
* ''Series/SpaceForce2020'': General Naird had frequent meetings with the Joint Chiefs of Staff where they frequently sniped at each other with insults. The only thing they all agreed on, was that even though the Space Force got little respect as the new branch, they still got more respect than the Coast Guard, who got NO respect.
* ''Series/{{Chuck}}'' had some friction between Casey (NSA) and Sarah (CIA) initially, but [[EarlyInstallmentWeirdness this dropped off after the first couple of episodes]]. However, any time the FBI showed up, both Sarah and Casey universally disparage them.
* In ''Series/{{Scrubs}}'', the rivalry between doctors and surgeons is a frequent RunningGag, with J.D. imagining the two groups in one episode as [[Film/WestSideStory1961 the Sharks and the Jets]]. The doctors of Sacred Heart take pride in being responsible for diagnosing patients' ailments and determining the correct treatment (which requires exceptional deductive reasoning skills and knowledge of the human body), while surgeons take pride in being responsible for performing the most complex and difficult medical procedures (which usually mean the difference between life and death). Accordingly, many doctors view surgeons as DumbMuscle whose only job is "cutting people up", while many surgeons view doctors as timid geeks who don't have the skills to handle truly risky procedures.

* ''TabletopGame/{{Exalted}}'':
** This is outright stated to be one of the Scarlet Empress's rules of government: divide and rule. [[TheEmpire The Realm]] has three different types of SecretPolice and eleven ''families'' of heirs.
** The CelestialBureaucracy. The Bureau of Heaven wants everybody answerable to them and keeps poaching promising gods or important purviews, the Bureau of Humanity catches flak for the general heavenly contempt for mankind and is the most heavily reassigned (the boundary between a human and universal abstract is considered flexible), the Bureau of Seasons hates the interference of the others who distrust it for its importance and its military power (which it is openly willing to use to force contentious matters of policy) and [[FantasticRacism looks down on it being largely staffed by Elementals]], the Bureau of Nature has the largest number of gods who need new assignments (since large sections of Creation and its lifeforms were recently destroyed) and is openly contemptuous of Yu-Shan's corruption (with them in turn sneering at its naivete and inefficiency), and everybody distrusts the Bureau of Destiny (being, as it is, responsible for developing the course of the future, having a lot of sensitive information, and including Exalted in its staff) while being forced to acknowledge how necessary its proper functions are for their continued survival.
* In ''TabletopGame/GURPSReignOfSteel'', the WASP agency and FBI of the Washington Protectorate have this trope going on. In the Machine Zones, some of the human resistance groups have been divided by internal rivalries, as well.
* In GURPS ''TabeltopGame/TranshumanSpace'', there's mention of a hard-fought battle in which the US Air Force gained supremacy in space. The battle was fought in the Pentagon and the enemy was the US Navy.
* Among the many company divisions of ''TabletopGame/SLAIndustries'', this trope is almost standard operating procedure.
* ''TabletopGame/MobileFrameZero'': Funny story. There are two groups known as "Marines" - the Terran Marines, who are frontline combatants, and the Transit Marines, who fight to defend the transit gates and in very few other situations. The Terran Marines ''really'' resent that the Transit Marines, who spend most of their time outside of combat, get to call themselves "Marines".
* This is a large part of what gets in the way of operational unity during the Second Star League's attempt to bring down Clan Smoke Jaguar in ''TabletopGame/BattleTech''. Made up of various House army units who had until then been spending bitter centuries fighting each other, they are then [[EnemyMine compelled to fight alongside age-old enemies in the name of overcoming much more brutal recent ones]]. As they are all under the aegis of the reconstituted Star League Defense Force, they are technically held under one government. This gets out of hand when hardline Steiner loyalists argue about command roles with traditionally Davion supporters, Liao units distrust members of the St. Ives regiments who seceded from Liao rule, ''any'' Marik force argues with ''itself'', and the Draconis Combine logistics arm favors Combine units above all others when they ''should'' be supplying gear and consumables to everyone.
** In a more general sense, the setting breaks down its armies by their role in combat, with different divisions for Dropship and Jumpship transportation and combat units. This is further split down based on the nature of combat units: [[HumongousMecha Battlemech]], [[TankGoodness ground armor]], [[CoolPlane Aerospace wings]], and infantry, both [[PowerArmor battle-armored]] and otherwise. The most notable traditional rivalries and squabbling in most armed forces in the setting so far shown have included: DropShip crews and [[FasterThanLightTravel Jumpship]] crews, Dropship crews and Aerospace pilots, Mechwarriors and Aerospace pilots, Mechwarriors and Dropship crews, Mechwarriors and tank crews, Mechwarriors and infantry units, and Mechwarriors and other Mechwarriors. And finally there's blue navy (that is to say, naval forces that are ocean-going ships rather than spaceships) vs everyone else, who tend to look down on water-based naval forces (not without reason) as being made up largely of spoiled nobles who want to have the prestige that comes with military service while avoiding any actual danger.
* In ''TabletopGame/{{GURPS}} Black Ops'', the Company is designed so that each department pulls in its own direction and has its own agenda for how best to protect the world. Notably, the [[TheBigGuy Combat]] and [[OmnidisciplinaryScientist Science]] departments ''hate'' each other, since Science's job is to capture and study Things That Go Bump In The Night, while Combat's job is to ''kill'' them. Other highlights are how almost everyone dislikes [[InternalAffairs Security]], Combat's characteristic orneriness (Combat, uniquely among departments, does ''not'' have a departmental directive requiring them to help the rest of the Company - because when the Company was set up, Combat was the spearpoint of most missions and everyone else was support), and an aversion in the overt ''friendship'' between [[CloakAndDagger Intelligence]] and [[GadgeteerGenius Technology]].

* ''VideoGame/MetalGear'':
** Briefly alluded to in the prologue of ''VideoGame/MetalGearSolid2SonsOfLiberty'', where the Marine Corps are conducting their own Metal Gear project independently, but about halfway through Snake notices an Army version of the Cypher UAV investigating the tanker. Commandant Dolph's speech in the holds likewise mentions heavy Navy opposition to Metal Gear RAY, both because it's in direct opposition to their Arsenal Gear project [[spoiler:which by the time of the Plant chapter leads them to hijack the RAY project and repurpose it as a defensive force ''for'' Arsenal Gear]], and that the strategic importance of aircraft carriers would likely be reduced by a weapon with RAY's capabilities.
** In ''VideoGame/MetalGearSolid3SnakeEater'', Snake's Virtuous Mission quickly degenerates into in-fighting between the Soviet KGB and GRU, which are pro-Khruschev and pro-Brezhnev respectively. The later Operation Snake Eater ends up being, in part, Khruschev asking for America's help in eliminating Volgin, who is a key member of the pre-Brezhnev faction.
** In the non-canon ''VideoGame/MetalGearGhostBabel'', the constant infighting between Army Chief of Staff John Parker and National Security Advisor Steve Gardner, who became bitter rivals after Gardner's zealous investigation of a case involving Parker's daughter only ended [[ItsPersonal when she committed suicide]], is perhaps the most major part of the game's backstory. [[spoiler:Many plot points in the actual story are a direct result of their bickering as well - perhaps most notably Black Chamber's betrayal, which was Gardner's demand in return for handing over control of the new Metal Gear's development to Parker.]]
* In ''VideoGame/ValkyriaChronicles'', the Army sees the Militia as a bunch of untrained field hands suitable only as cannon fodder, and the Militia sees the Army as a bunch of incompetent aristocrats whose social status is the result of overt nepotism. This is shown again in ''VideoGame/ValkyriaChronicles4'', where members of Squad E and the Federation army come into conflict with the Navy multiple times after [[spoiler: Operation Northern Cross fails and they join up with [[CoolBoat the Centurion]].]]
* ''Franchise/FinalFantasy''
** For ''VideoGame/FinalFantasyVII'', while it seemed as if the divisions were pretty spiffy with each other in the original game, ''VideoGame/CrisisCore'' showed that [[CorruptCorporateExecutive Shinra]] corps seemed to be in a constant state of war. The mook Midgar security soldiers didn't like the more attention hogging [=SOLDIERs=], the mooks ignore Turk instructions in lieu of getting more rewards for themselves, the [=SOLDIERs=] treat the smaller foot soldiers as nothing better than CannonFodder... the dynamics of which contributed highly to [[spoiler:Zack's death in the end, as the soldiers rushed forth to execute Zack before the Turks arrived at the scene]].
** In ''VideoGame/FinalFantasyX'', both the Crusaders and Warrior Monks are arms of the [[CorruptChurch theocratic Church of Yevon]]; however, several Warrior Monks speak disdainfully of the Crusaders, making it clear that they consider the Crusaders only a few steps away from being heretics, while considering themselves the true defenders of the faith.
** ''VideoGame/FinalFantasyXIII'': Cocoon's military is divided into the Guardian Corps, who are assigned to specific regions of Cocoon, and PSICOM, who are officially an anti-Pulse task force. Whenever something Pulse-related surfaces in Cocoon, PSICOM tends to show up and appropriate operations, to the GC's disdain.
* ''Franchise/{{Halo}}'':
** The [[SuperSoldier Spartan-IIs]] and the [[BadassNormal ODSTs]]. Before the Spartans came into the picture, the Orbital Drop Shock Troopers were the elites of the United Nations Space Command Defence Forces, so when the Spartans took over as the elite, the [=ODSTs=] weren't happy about it. What was more insulting to them was that, when John-117 killed two ODST troopers in a gym in his earlier ages, he wasn't punished for it (because the ODST troopers started the whole thing and John only defended himself). Ever since then, the [=ODSTs=] haven't seen the Spartans as anything more than "freaks", "cyborgs" and as "non-humans", due to the Spartans' special powers and superiority over the "normal" human beings. It ain't getting better considering the Spartans seems to have more respect from the other marines than them, even if the Spartans are actually a part of the Navy (being closer to elite [=SEALs=] than SpaceMarines). The Spartans themselves, however, [[UnknownRival don't really care about the rivalry at all]]. They just want to get the job done. Funnily enough, with the creation of the SPARTAN-IV Program, many [=ODSTs=] have gone on to become Spartans themselves.
** This becomes a plot point in ''VideoGame/Halo2'' when the rivalry between the Sangheili (Elites) and the Jiralhanae (Brutes) within the Covenant breaks out to an [[EnemyCivilWar open civil war]] - one that [[BigBad the Prophet of Truth]] deliberately provoked in order to replace the Elites with the Brutes as his leading troops, as he considers the Elites' extreme reliance on their code of honor as a hindrance to their direct loyalty to him,[[note]]indeed, it's mentioned in background material that the Elites have questioned more than once ''why'' the Covenant hasn't tried to incorporate humanity into themselves rather than wipe them out entirely[[/note]] while the Brutes almost never question orders [[BloodKnight as long as it involves killing something]], with the other species' loyalty splintered. This causes the Elites [[HeelRaceTurn to ally themselves with UNSC]], [[TheCavalry turning the war to their favour and together, they finally kill Truth and destroy the Covenant once and for all]].
*** This is even subtly alluded to in ''VideoGame/HaloReach''. The Elites and the Brutes ''never'' appear fighting side by side, the Elites will only arrive after all the Brutes have been killed; with the implication being that the Elite commanders in charge of the invasion are using the Brutes to soften up the opposition before sending their own people in. This can be seen in both "The Package" and "The Pillar of Aututmn", where despite the stakes the Elites would seemingly rather have Brutes die first than coordinate their assaults.
** The novels state there is also a rivalry between the Unggoy (Grunts) and Kig-Yar (Jackals), though it isn't nearly as intense as the one the Elites and Brutes have. Or at least, due to these races being lower in the FantasticCasteSystem, not as important. At least one time on record the Jackals attempted to sterilize the Grunt population due to incidents involving the Grunts accidentally infringing on and destroying Jackal eggs in their nesting grounds, which led to at least one Grunt Rebellion as a whole.
** ''Literature/HaloGlasslands'' alludes to a slight rivalry between the Spartan-[=IIs=] and Spartan-[=IIIs=]. For the most part, though, they see each other as fellow Spartans, and work together on several occasions, including in ''VideoGame/HaloReach'' where the otherwise-all-Spartan-III Noble Team has a Spartan-II as TheBigGuy. The only one who really objects to the Spartan-[=IIIs=], as it turns out, is Catherine Halsey, who is apparently trying to discourage them from fighting because she sees the Human-Covenant War as unwinnable.
* In ''VideoGame/RuneScape'', the Imperial Guard view the Knights of Falador as a rival military force in the Kingdom of Asgarnia.
** It should be noted that their "rivalry" is just a push away from civil war. The White Knights are a religious order in service of [[LightIsNotGood Saradomin]], the god of order, and have traditionally been allied with the Crown. Currently, they are ruling over Falador - the kingdom's capital - [[TheCoup during the king's "illness"]]. On the other hand, the Imperial Guard is a secular army loyal to the Crown Prince who hold residence in the principality of Burthope where they are defending Asgarnia against invading trolls while White Knights are waiting for any excuse to take over.

* In ''VideoGame/{{Xenonauts}}'' the head scientist snipes at the engineers in his Xenopedia articles.
-->'''[[DoingResearch Research report]]:''' The resulting interceptor is squat, ugly, and capable of destroying almost anything it encounters (much like our engineers).

* ''VideoGame/XCOMEnemyUnknown'' has a rivalry between Dr. Vahlen and the Scientists, and [[CoolOldGuy Dr. Shen]] and the Engineers. They don't openly snipe at each other, but they often strongly disagree on things like what action the player should take and what projects should be developed. Taken further in ''Enemy Within'', where they're still going at it: they keep trying to entice the player towards a certain use of [[AppliedPhlebotinum Meld]], with Vahlen championing GeneticEngineeringIsTheNewNuke, and Shen championing good ol' {{cyb|org}}ernetic implants. Hilariously lampshaded by your NumberTwo, who asks them if they agreed on anything, and they both answer ''the name''.
* ''VideoGame/GrandTheftAutoV'': A large chunk of the game's plot centers on an interservice ''war'' between the [[FunWithAcronyms FIB]] (FBI-{{expy}}) and IAA (UsefulNotes/{{CIA}}-expy) over who should receive more government funding now that UsefulNotes/TheWarOnTerror is winding down, with both sides going to rather depraved extremes to make themselves look better than the other. It's [[PlayedForDrama more serious]] than most examples since both sides are playing with other peoples' lives to further their own goals.

* This is quite common in ''VideoGame/StarWarsTheOldRepublic''. Especially in the [[TheEmpire Sith Empire]]. It's even encouraged among the Sith Order. It's quite common for a Sith Apprentice to kill their Master [[KlingonPromotion and gain their titles.]]
** Sith Rivalries are quite frequent as shown in the Warrior and Inquisitor storylines. Both start on Korriban where acolytes frequently compete to become Sith. Acolytes are forbidden from killing each other with witnesses around. But if someone were to die or suffer an... accident in the tombs while no one was watching, well, nobody would investigate. Unless a Lord demands it, of course.
*** The Sith Warrior already starts out with an enemy: Vemrin. While the Inquisitor competes in a group, their most fierce rival is Ffon, whom the Overseer showers with endless praise.
*** The Sith Inquisitor runs into multiple of these. On Dromund Kaas their master Lord Zash orders them to assassinate a rival, Darth Skotia. After Zash [[spoiler:tries to pull a GrandTheftMe on the Inquisitor and fails]], her own master Darth Thanaton, a Dark Council member, tries to outright murder the PC based on little more than his reading of Sith traditions: that Sith cannot be ex-slaves, and that the entire power base of a fallen Sith Lord must be destroyed for the good of the Empire. As a consequence Thanaton and the PC spend the entirety of Chapters 2 and 3 trying to kill each other, which escalates into a mini-CivilWar by the end. Finally, in Chapter 3, [[spoiler:the Inquisitor's last Companion, [[TheQuietOne Xalek]], ruthlessly kills a Twi'lek with his bare hands, takes the last artifact from his corpse, and gives it to the player, right in front of everyone. Nevertheless, the Inquisitor insists on having Xalek as an apprentice and has the option of killing Harkun for defiance (and revenge)]].
** In the Sith Warrior Storyline an Imperial Moff named Masken [[spoiler: claims that Baras deliberately set up an ambush for his master, Vengean, because the invaders had the docking codes for the flagship.]] He even expresses his discontentment at this ridiculous infighting, claiming it to be the reason they haven't beaten the Republic. [[spoiler: Ironically, if the Warrior decides to just leave after repelling the invaders, the Moff hypocritically attacks you claiming that he will be rewarded.]]
** Meanwhile, over in the Imperial Agent storyline, Imperial Intelligence more or less views itself as the OnlySaneMan: while technically answering to the Sith, they frequently find themselves having to clean up the dark Jedis' messes when they act out ForTheEvulz. Early in the storyline, in order to salvage their mission on Hutta, the PC has to kill or drive off an asset they were developing after a Sith Apprentice gets in an offscreen fight with his sons and kills one of them. The regular Imperial military (not represented by a PlayerCharacter) has some of the same problems: they tend not to like it when the Sith intervene in military operations, because even if ''some'' Sith such as Darth Decimus are legitimately good commanders, many are some combination of arrogant, capricious, backstabbing, and/or incompetent.
* ''VideoGame/TheElderScrollsIIIMorrowind'':
** The [[CorruptChurch Tribunal Temple]] has two militant wings: the ChurchPolice Ordinators, who serve as guards for Temple holdings and holy sites, inquisitors, and jailers, with KnightTemplar traits, and the Buoyant Armigers, elite special forces handpicked for service by [[PhysicalGod Vivec]] himself, who are typically decked out in high quality glass armor and typically operate in the {{Lethal Lava Land}}s and {{Mordor}}s of Vvardenfell. The more solemn Ordinators don't really get along with the Armigers, who seek to emulate Vivec's WarriorPoet traits.
** In the ''Tribunal'' expansion, there is a rivalry and general sense of distrust between [[PhysicalGod Almalexia's]] High Ordinators and [[MagnificentBastard King Helseth's]] Royal Guards. [[spoiler: When the city is attacked by fabricants, each faction will ask you to report the attack to their side's leadership]]. The quests in the second half of the Tribunal main quest are slightly different depending on which side you report to, though the ending is ultimately the same.

* ''VideoGame/CommandAndConquerRedAlert3'':
** While it's mentioned that the usual rivalries between air force and ground troops are present, said ground troops have nothing but respect for Vindicator bombers, since they probably had their life saved by one at some point. The other sticking point (air forces having access to more creature comforts than ground troops) is also averted since Vindicator pilots are posted on the front lines and so live in the same conditions as the groundpounders.
** The Century Bomber pilots are treated neutrally, because they are also posted at the front but bomb bases rather than provide close air support.
** Played straight with the Harbinger, a monstrously huge and powerful gunship aircraft whose pilots are viewed with suspicion and distaste by ''other pilots'' of all people. This apparently stems from Futuretech running its own flight schools rather than let experienced pilots use it. Granted, given the fact that the ordnance on board is just barely this side of a WMD it's understandable.
** The various generals and admirals despise each other to varying degrees, in the most extreme instance two of the Japanese generals literally go to war over an honor dispute.

* Parodied in ''Webcomic/JetDream.'' ''It's Cookie!'' features two [[TeenSuperspy teenage]] Soviet bad guys: [[UsefulNotes/MoscowCentre KGB]] agent "He-She Svetlana", and {{UsefulNotes/GRU}} "Saboteen" Captain Boris Volkov. The two can't stand each other, and in "The He-She Ski Affair", their respective organizations are also working at cross-purposes -- the GRU wants to capture and interrogate Cookie Jarr, while the KGB wants to assassinate her.
* In the ''Webcomic/SkinHorse'' storyline "I Can Fly", General Sal thinks of Skin Horse as civilians with a grudge against the military. When Tip points out he's ex-Army, she expresses disbelief (since he's a WholesomeCrossdresser) and he replies "Well, I wouldn't expect ''Air Force'' to understand."

* In ''WesternAnimation/{{Recess}}'', the Army/Navy rivalry appears in the form of the rivalry between Gus Griswold's Army general father and Corn Chip Girl's Navy admiral father. Which handily set up the StarCrossedLovers (or at least [[NoHuggingNoKissing Star Crossed Friendship]]) plot.

* In ''Manga/GunslingerGirl'', the members of Sections 1 and 2 have one of these. For some reason, Section 1 finds the concept of cyborg little girls used as a death squad somehow ''weird''. Because Section 1 consists of adult male human operatives, who are not happy about being upstaged by half-mechanical little girls.
* Various divisions of the TSAB in ''Anime/MagicalGirlLyricalNanohaStrikers''. In particular, the Ground Forces' commander hates Riot Force 6 (which is a cross-service special forces battalion assigned to a paramilitary LostTechnology control division). The fact that the commander and half of [=RF6's=] staff are former criminals that one member of the team [[DefeatEqualsFriendship blasted into submission]] does not help.
* The Public Security Division and the Kerberos Unit have an intense one going on in ''[[Anime/JinRohTheWolfBrigade Jin-Roh]]''. PlayedForDrama, as the rivalry is escalating at a worrying rate. [[spoiler:In fact, the entire plot was brought about by it; Kei is really a Public Security agent and her romance with Fuse was staged to try and create a fake scandal that would let the PSD shut down the Kerberos Unit. Unfortunately for them, Kerberos know about the scheme and out-manipulate the PSD, killing Kei and several other agents while blackmailing the PSD into standing down.]]

* ''Franchise/GhostInTheShell'', especially in ''Anime/GhostInTheShellStandAloneComplex''. Their own government and other branches of service are a far greater threat to Section 9 than any external enemy could ever hope to be.
* ''All over the place'' in ''Anime/MaoChan'', where the heads of the three branches of the defense force are all old friends... who are [[TheRival constantly competing]], [[VitriolicBestBuds often viciously]].
* In ''Anime/{{Hellsing}}'', most other branches of law enforcement seem to dislike the Hellsing Organization. At one point the SAS clash with Hellsing over jurisdiction over a case involving Incognito, resulting in an entire SAS squadron being captured by the BigBad.

* Some divisions of the Gotei 13 in ''Manga/{{Bleach}}'' have this, especially the [[TheMedic 4th ]]and [[BloodKnight 11th ]] divisions; the former views the latter as a gang of violent thugs and the latter views the former as weak and useless in battle. When Ichigo and Ganju take Hanataro of the 4th Division hostage, the 11th Division {{Mook}}s pursuing them laugh it off.

* ''Manga/BlackLagoon: Roberta's Blood Trail'' inflamed a behind-the-scenes rivalry between the NSA and CIA over jurisdictions from South America to the Southeast Pacific. Had Roberta not intervened and become ''everyone''[='=]s problem, Roanapur probably would've come under pressure from the upstart agency. As it was, the CIA, and their interests in Roanapur, were able to maintain the status quo.
* ''Manga/AttackOnTitan'':
** The civilization within the walls has three military branches (Military Police Brigade, Survey Corps and Garrison), and all three view each other with suspicion to the point that the (corrupt) Police Brigade thinks the Survey Corps wants [[spoiler:the Rogue Titan aka Eren]] to seize power from the inner circle from them. It doesn't help that there is a distinction between the highly regarded Police Brigade and TheUnfavorite Survey Corps who do most of the fighting. [[spoiler:The rivalry between the Police Brigade and the Survey Corps ultimately boils over into open warfare, after a [[SecretPolice special unit]] of the Military Police and the nobles who back them, attempt to seize Eren's power for themselves and wipe out the Survey Corps, which by that point includes most of the main characters. The Survey Corps gets the Garrison on their side with evidence of the corruption and self-serving nature of the nobility and then launches a coup to oust the corrupt government and Police Brigade from power]].
** When we eventually see [[spoiler:the Marleyan military]], it becomes clear that they have some deep divisions, most notably [[spoiler:there is a fairly bitter divide between their army and navy. Also, it practically goes without saying since Marley is ''built'' on institutional, FantasticRacism, but regular Marley units have contempt for their Eldian counterparts that serve alongside them.]]
* In ''Anime/MobileSuitGundam'', this was the problem with Zeon flat out. Everyone was trying to top everyone else, leading to double crosses, delays in important supplies, rivalries between ''production lines'' and, ultimately, the loss of good pilots. A microcosm of this happens with Ramba Ral: when he lost his Gouf [[HumongousMecha mobile suit]], he requested the new model Dom as a replacement. Unfortunately, the man in charge of requisitions was M'Quve, who served under a different commander[[note]]Ral served under Dozle Zabi, M'Quve under Kycilia[[/note]] and refused Ral's request purely for political reasons. As a result, Ral lead a desperate guerilla attack on White Base that resulted in his death. Had he gotten the Doms, he could have potentially defeated the Gundam -- if not alone, then he could have teamed up with the Black Tri-Stars (another group of ace pilots) and won with ease; instead, the Tri-Stars were picked off one by one, as Amuro had become an even better pilot by the time they showed up.
* ''Anime/MobileSuitGundamIronBloodedOrphans'': Because Gjallarhorn's forces are divided between rival aristocrat families, clashes between the different branches of the Gjallarhorn military are relatively common as they're all making plays to expand their spheres of influence. This reaches its head late into Season 2, when [=McGillis=]'s gambits to expand the Outer Earth Orbit Regulatory Joint Fleet's power lead to Rustal Elion and his Arianrhod Fleet working to undermine him, eventually resulting in [[spoiler:a full blown CivilWar within Gjallarhorn]].
* In ''Anime/MobileSuitZetaGundam'', this is part of the animosity between the Earth Federation Forces and [[StateSec the Titans]]. The Titans, being an elite corps designed to protect the Earth from any Zeon resistance, take the lion's share of, well, ''everything'' - money, Mobile Suits, prestige, etc. As a Titans member is considered two ranks higher than an Earth Federation member of the same rank, they turn into massive bullies that lord over everyone else on top of the regular folk.
* In ''Literature/FullMetalPanic: The Second Raid'' Melissa Mao tells the story of how she escaped from an ArrangedMarriage by joining the U.S. Marine Corps, marching into the recruitment office [[RunawayBride still wearing her wedding dress]]. The recruiters were reluctant to sign her up until Mao revealed that her father was a Colonel in the Air Force, at which point they welcomed her into the Corps purely to annoy him.
* ''Manga/VinlandSaga'', particularly in the early episodes of the anime, show that there is a definite gulf between the normal Danish soldiers and the vikings (who the series points out are the equivalent of pirates and thieves) and mercenaries being enlisted by the Danish monarchy to assist in conquering England. Going by a few interactions, it's pretty clear that the regular Danish soldiers view vikings as greedy, unscrupulous, unreliable, and just generally more trouble than they're worth, while the vikings see the soldiers as stodgy, arrogant, and ineffective.
* ''Manga/OnePiece'': For the most part, both the Marines and [[StateSec Cipher Pol]] get along well when it comes to crusading against piracy and serving the World Government. However, tensions sometimes crop up when it comes to the main goals of each organization. The Marines are focused primarily on stopping piracy and maintaining the security of the World Government and its member states. In contrast, Cipher Pol is primarily focused on serving the political interests of the World Government first and only stopping pirates and other criminals as a secondary objective.[[note]]The exception is if the mission a CP Agent is given specifically involves dealing with pirates/criminals that are considered political threats and/or threats large enough to warrant assassination.[[/note]] As a result, clashes sometimes occur in which Marines and CP agents will not hesitate to try and kill each other during their respective missions. A good example is during the Enies Lobby Arc, when Vice Admiral Onigumo ordered his ships to open fire on the ship Luffy and Lucci were fighting on in an attempt to kill Luffy, and just before that, Lucci threatened to kill the Marines onboard the ship if they got in the way of his fight.
** The Wano Country arc introduces SWORD, a group of young marines which [[spoiler:Coby and X Drake]] are a members of. While SWORD and Cipher Pol are both part of the World Government, the two organizations don't get along terribly well. The organizations don't share information with each other and have a lot of ideological differences, leading to quite a bit of tension on both ends.

* ComicBook/NickFury (a former Army Ranger) is known to make comments pertaining to "deck monkeys" and "candy-ass marines".
* During Gung-Ho's first appearance in the ComicBook/GIJoe comic, Rock'N'Roll was notoriously pissed to have a marine in the team.

* ''Comicbook/TheAvengers'': [[ComicBook/MsMarvel Captain Marvel]] (U.S. Air Force veteran Carol Danvers) and Comicbook/CaptainAmerica (U.S. Army veteran Steve Rogers) have been shown trading jabs about their respective services. This is a little odd, given that when Capatain America was in the Army, the Air Force had not yet been made its own branch of the armed services and was instead still part of the army.
* Jay Faerber's ''ComicBook/Dynamo5'' features F.L.A.G. (the Foundation for Law and Government), which is responsible for superhero activity in the United States. Robert Kirkman's ''Invincible'' features the G.D.A. (Global Defence Agency) which is responsible for protecting the Earth from superhuman and extraterrestrial threats, and has at least one superhero team on its payroll. They don't get on too well.

* In ''ComicBook/{{Drowntown}}'', the police and Admiralty Intelligence don't seem to get along. When Hammond (a cop) runs a database check as a favour to Leo, Admiralty Intelligence comes to find out who's digging, but are promptly stonewalled by the cops (at least until Leo tells Hammond to let it go).

* ''ComicBook/{{Monstress}}'': The Federation Navy and the Federation Army despise one another to the point that when war reignites, the Federation Navy immediately begins leaking exact troop deployment information to the Arcanics. The Navy also appears to have taken the [[CorruptChurch Cumaea's]] purges of Arcanic personnel ''much'' worse than the Army did, such that it's in question if they'll join the fight -- or even outright defect to the Arcanics.

* ''Fanfic/TheElementsOfHarmonyAndTheSaviorOfWorlds'' has a small example that's played mostly straight but ultimately subverted. When Big Macintosh first meets Shining Armor, he initially doesn't like him, since -- having done a tour of duty in the main Equestrian army (tanks corps, specifically) -- he views the Royal Guard as "little wimps and nobleponies playing at being soldiers". Thing is, Shining ''agrees'' with him, having been a part of the main army before being made Captain of the Guard specifically to whip it back into shape. After this conversation, he and Mac get along fairly well.
* Speaking of Shining Armor, he gets another example, this time played for laughs, in the ''Fanfic/PonyPOVSeries''. He tells the interviewers that he sees interservice rivalry as being good for morale... literally seconds after offhandedly describing the Day Guard as wimps and saying that the Night Guard is scared of the light. He also completely ignores the fact that he ''was'' a Day Guard before being reassigned to lead the new branch dedicated to Cadence.
* ''Fanfic/DeathNoteEquestria'': There's quite a bit of friction between the Royal Guard and the Canterlot City Guard (police) over the Kira investigation.
** Straw Bolt (Captain of the Canterlot City Guard) also ''really'' doesn't like L or her methods.
* Some Interservice Rivalry crops up from time to time in ''Fanfic/StrikeWitchesQuest'', though the Martian War and shared hatred of brassholes can cause [[EnemyMine bitter rivals to temporarily ally]].
* Specifically invoked by [[spoiler: [[TheChessmaster Mercury]] ]] in [[https://www.fanfiction.net/s/9998018/1/Phoenix-fire Phoenix-fire]]. [[DoesThisRemindYouOfAnything The army has an ongoing rivalry with the navy]], and the airspace is being set up to be divided between the Knight-Wings [[spoiler: (lehtrblaka with riders)]] and [[spoiler: captured and ''"reformed"'' dragon riders]]. All done to ensure that in the case of a coup, no faction could ever fully control more than one theater of battle.

* The MLP AbridgedSeries ''WebVideo/ScootertrixTheAbridged'' has this between its version of the [[ChildSoldiers CMC]].

* In ''Fanfic/CodeGeassLelouchOfBritannia'', Lelouch gains some favors from the Army high command by using his tactical genius to allow the underdog cadets to defeat the midshipmen at the Army-Navy football game.
* In ''Fanfic/TheMisfitsSeries'', the antagonism between the X-Men and the Brotherhood has become this when the latter are adopted and rechristened by the G.I. Joes as the Misfits. While both groups fight against villains, including Magneto and Cobra, they rarely, if ever, get along.

* ''Fanfic/SixesAndSevens'': In "Agent Carter: Phantom Pain" the rivalry between the Secret Intelligence Service and the Special Operations Executive has gotten completely out of control and violent, due to differing opinions on what Britain's post-war, and post-imperial, role should be.
* Between Professor George Dunder and General James Ironwood in ''Fanfic/DustAndDecepticons''. The two represent the Huntsman system and military of Atlas respectively, and they both despise each other. George accuses Ironwood of having played a role in getting his best Huntress team killed. Ironwood, for his part, covers evidence of Cybertronian activity in Atlas and tries to keep George from getting involved so he doesn't discover them.

* For ''VideoGame/FinalFantasyVII'', while it seemed as if the divisions were pretty spiffy with each other in the original game, ''VideoGame/CrisisCore'' showed that [[CorruptCorporateExecutive Shinra]] corps seemed to be in a constant state of war. The mook Midgar security soldiers didn't like the more attention hogging [=SOLDIERs=], the mooks ignore Turk instructions in lieu of getting more rewards for themselves, the [=SOLDIERs=] treat the smaller foot soldiers as nothing better than CannonFodder... the dynamics of which contributed highly to [[spoiler:Zack's death in the end, as the soldiers rushed forth to execute Zack before the Turks arrived at the scene]].

* In ''VideoGame/FinalFantasyX'', both the Crusaders and Warrior Monks are arms of the [[CorruptChurch theocratic Church of Yevon]]; however, several Warrior Monks speak disdainfully of the Crusaders, making it clear that they consider the Crusaders only a few steps away from being heretics, while considering themselves the true defenders of the faith.

** The non-canon ''VideoGame/MetalGearGhostBabel'' has as a major part of its backstory the constant infighting between Army Chief of Staff John Parker and National Security Advisor Steve Gardner, who became bitter rivals after Gardner's zealous investigation of a case involving Parker's daughter only ended [[ItsPersonal when she committed suicide]]. [[spoiler:It plays into the main story as well, as many plot points are a direct result of their bickering - perhaps most notably Black Chamber's betrayal, which was Gardner's demand in return for handing over control of the new Metal Gear's development to Parker.]]

Cases of Interservice Rivalry can cause JurisdictionFriction and DividedWeFall. Compare RightHandVersusLeftHand. See also CIAEvilFBIGood, in cases where a moral contrast between the two is depicted. There is also TruthInTelevision to this.
