A commanding officer -- who may be [[YouAreInCommandNow in command now]] or may hold the correct rank for his position -- sorely lacks in senior officers. Perhaps they're TrappedBehindEnemyLines. Or communications are shot to hell. Or the senior officers were treacherously invited to a NastyParty. Or he's piecing together something resembling a unit out of the shattered remains of an army. Any suitable disaster to remove them will do.

He must brevet many juniors. Expect some of them to panic for at least a minute or two. May also inspire moments of grief because their predecessor is dead -- hopefully, no matter how beloved he was, not LosingTheTeamSpirit.

If the [[http://en.wikipedia.org/wiki/Brevet_%28military%29 brevet rank]] doesn't stick, it still tends to be an advantage for future [[RankUp promotions]]. And it often does, because mortality weeded out the senior ranks, and because the jump is often not that great. There is often a ripple effect: brevet a captain to major; brevet a lieutenant to captain to replace him; brevet a sergeant to lieutenant to replace him; and finally, brevet a private to sergeant to replace ''him''. Normally, under this trope, their existing ranks are not put out of order; the sergeant doesn't become the major over the head of a lieutenant, etc.

A slightly less chaotic situation may result in actual promotions as needed to fill the gaps, [[http://en.wikipedia.org/wiki/Battlefield_promotion the actual field -- or battlefield -- promotions]].

Closely related to ClosestThingWeGot, and in fact many stories with Field Promotion also use that trope.

If you have no one left to promote you, YouAreInCommandNow instead.

[[folder:Anime]]
* In the Original ''{{Macross}}'' Anime series, Captain Gloval (old tough veteran of the unification wars) laments the inexperience of his crew when the newly rebuilt and untested superdimensional fortress comes under sudden attack from mysterious aliens at the start of the series.

[[folder:Comic Books]]
* The eponymous ''Comicbook/SgtRock'', of course, started out as a buck private, and while many of his actions were considered worthy of promotion, Easy Company's TO was apparently full. Until a certain battle, whereupon as fatalities accumulated, he was promoted to PFC, Corporal, and finally Sergeant in short order. Not how he would have preferred to earn his stripes, to say the least.
* In the JudgeDredd series ''The Pit'', the eponymous character promotes a cadet to full judge.
* In ''[[StarWars Star Wars: Empire: To the Last Man]]'' an Imperial Army column gets surrounded by native warriors and faces destruction. As the casualties mount, General Ziering promotes Lieutenant Janek Sunber to Captain and eventually Commander. When Lt. Sunber manages to get back to headquarters the only other surviving officer refuses to verify his promotion and he gets bumped back down to Lieutenant due to the other officer being envious of the man's bravery, competence, and favor with the general - he refuses to verify the field-promotions just to spite him.
* In ''ComicBook/{{Asterix}} and the Chieftain's Shield'', Ceasar orders that the eponomyous shield, which was stolen following his victory at Alesia, be found so that he can be carried on it in front of the rebellious Gauls as a symbol of his victory over them. He orders the Prefect of Arverne to find it and every Roman soldier in the city begin desperately searching the numerous coal sheds in town to find it. At the end of the book it turns out Vitalstatistix has it and the town parades in front of Ceasar lead by him and Asterix, while the soot-covered Romans are left on the sidelines. Ceasar promotes the only two clean soldiers in the city (a drunken Centurion and a slacker Legionnaire), who ducked out of the search, to Prefect and Centurion respectively and leaves, saying that [[LetUsNeverSpeakOfThisAgain no-one shall ever mention these events or this town in his presence again]].

[[folder:Fan Works]]
* In chapter 9 of ''[[http://web.archive.org/web/20031203155746/sfvskof.highervoltage.net/intro.php Nightmare Symbiosis]]'', M. Bison's personal transportation flies through a massive storm/PillarOfLight [[spoiler:generated by Orochi]]. A pilot by the name of Stanton panics, which leads to Bison killing him. He turns to the next in the chain of command, a pilot named Amy Redding:
-->'''Bison''': ''(jovial)'' Miss Redding, I am delighted to inform you of your promotion~ ''(cold)'' Do ''his'' job better than ''he'' did.
* In ''FanFic/MegaManDefenderOfTheHumanRace'', [=ProtoMan=] talks Wily into putting him in command of the Robot Masters and operations in the interlude to episode 9.
* Very odd example from ''FanFic/TheWorldsGreatestChuninExamTeam''. Killer B is still a Genin but as he explains to Naruto, he was a genin during the Third Shinobi World War. At some point, he became a squad leader and started getting treated like a jonin. This happened for so long that the ninja in Kumo still treat him like one and have forgotten that they never made it official.
* Before "Fanfic/TheUniverseDoesntCheat" Eleya was brevetted up to lieutenant commander, apparently the minimum rank before you can command a starship. This after she [[YouAreInCommandNow ended up the seniormost officer left alive]] courtesy of the Borg. Admiral Arkad makes the promotion permanent at the end of the story.
[[/folder]]

[[folder:Film]]
* One of Darth Vader's trademarks in ''TheEmpireStrikesBack''. In one scene, [[YouHaveFailedMe he chokes the idiotic Admiral Ozzel]], and immediately addresses Captain Piett as Admiral Piett, [[YouAreInCommandNow putting him in command right then and there]]. And with the previous Admiral ''still choking in the background'', there's a very tacit reminder of the consequences of messing up.
** Meanwhile, the trap at Cloud City fails, but Vader's reaction is different--more disappointment and sadness than anger--so Piett goes on to be one of three Imperial characters to appear in more than one movie in the original trilogy.
*** And it was not because of Piett's planning, plus he wasn't a jerk about it. Ozzel wasn't so smart when he decided that [[TooDumbToLive being arrogant to Vader was a smart idea]].
* Creator/JossWhedon seems to have [[FlipFlopOfGod changed his mind on the subject a time or two]], but there are hints in ''Film/{{Serenity}}'' and its novelization that main character Sergeant Malcolm Reynolds got a brevet promotion up to Captain during the Battle of Serenity Valley. Certainly he was ''commanding'' as many men as a captain would by the end.
** The series also did a very dark take on the more usual sort of Field Promotion. When Mal is trying to get some air support for himself and his men, he is told that the cover won't come without a Lieutenant's orders. Mal promptly walks over to the body of Lieutenant Baker, tears off the patch of his uniform with his authorization code, and hands it back to the person he was talking to, saying "Here, you're Lieutenant Baker. Congratulations on your promotion, now get us some air support!"
* In the Canadian ''Film/{{Passchendaele}}'', about the bloody UsefulNotes/WorldWarI battle of the same name, the senior commander of the Allied forces is forced to do this repeatedly as his immediate subordinate officers are being killed left and right by enemy fire.
* Variation in ''Film/KingdomOfHeaven'': Balian actually knights every single soldier in Jerusalem right before the final battle. [[spoiler:Which they lose, so it probably didn't help...]]
** TruthinTelevision: The real Balian knighted sixty bourgeoisie (middle class) men because there were a grand total of two knights in the city. The film portrays him as being extremely generous knighting freemen and serf alike, mostly for the psychological boost. [[spoiler:He wasn't trying to win the battle, he was hoping to hold out long enough for Saladin to negotiate instead of just trying to kill everybody.]]
* The rebooted ''Franchise/StarTrek'' [[Film/StarTrek film]] of 2009 gets most of the senior officers of the USS ''Enterprise''--including ''two'' captains--into their billets in this way.
** Actually, ''three'' captains. [[spoiler:George Kirk, Spock, and James Kirk.]] Although you could argue that that last one is more a combination of [[spoiler:YouAreInCommandNow and KlingonPromotion]].
* In the film version of ''Film/StarshipTroopers'' the protagonist's unit is all but destroyed during the initial invasion. Reforming afterward under a new commander, the protagonist is promoted not once but ''twice'' in one day, going straight from grunt to lieutenant and commander of the unit. All of this with only basic training. He then proceeds to hand out yet more field promotions, despite the fact that his most senior members have only have two actual experiences in the field. For info about how things happen in the book, see the Literature tab below.
* In the movie ''Film/WhenTrumpetsFade'', set in the battle of the Hurtgen Forest in 1944, the main character starts the movie at the rank of PVT (E-2). Due to the extreme attrition (33,000 Americans were lost in the battle), he is involuntarily promoted to Sergeant (E-5) and made a squad leader on the promise that should he survive he will be evacuated for battle fatigue and given a Section-8 discharge. The evacuation and discharge never happens, and then due again to attrition and the mental breakdown of his platoon leader, he is involuntarily promoted to 2Lt (O-1). This is an example of Truth in Television, as the Battle for the Hurtgen Forest in reality lasted 5 months (the longest battle in US military history) and was enormously bloody with greater than 25% casualties suffered by American forces and many smaller units entirely annihilated. Men who entered the Forest in September of 1944 as privates were almost guaranteed to leave at significantly higher rank if they survived until the battles conclusion in February 1945. Two entire US divisions, the 4th and 9th Infantry could not even use battle field promotions to replace all of the lost NCO's and officers, and were forced to withdraw from combat to rebuild.
* In ''Film/{{Patton}}'', Patton does this during the Sicilian campaign when a local commander is directing his troops too slowly for his liking, promoting an executive officer to commanding officer. If he doesn't make it through in one hour, he's fired too.
* In ''Film/TheLongestDay'', [=BGen.=] Norman Cota (Robert Mitchum) finds that the highest ranking Army engineer on Omaha Beach is Sgt. John H. Fuller. He promotes him to Lieutenant and puts him in charge of demolishing a concrete barrier.

[[folder:Literature]]
* Creator/SandyMitchell's Literature/CiaphasCain novels have several instances of this:
** The series begins with the Valhallan 597th being pieced together from two regiments torn up in combat with Tyranids, with the rush of promotions that situation implies. Some regiments are worse off than others, though - mention is made of a Lieutenant promoted directly to colonel, [[YouAreInCommandNow by default]]. Even worse, her second-in-command (Who had considerably more combat experience than Colonel Kasteen) lost out on the promotion because she had ''three days'' seniority over him. And of course, merging an all-female regiment with an all-male one brings its own problems...
** In ''Death or Glory'', he promotes a lieutenant and a sergeant to manage his ramshackle army, and two artisans are assigned to help their only engineer (they end up becoming lay brothers of the Mechanicus cult later).
*** The book also notes that these promotions would have to be finalized by the actual army since Cain as a Commissar is not inside the chain of command. However, denying promotions handed out by a Commissar would likely bring the attention of the Commissariat, which no one really wants...
** Jenit Sulla gets a variation: instead of a straight promotion, she gets breveted to the position, which gives her a trial run (if she fails, it doesn't leave a demotion on her record). To Cain's surprise, it sticks.
** In ''Cain's Last Stand'', he brevets the commissars in training as commissars. At the end, he ensures that all the survivors actually hold that rank.
* ''Literature/StarshipTroopers'': Several examples:
** There is one bit where fresh-out-of-the-Academy Third Lieutenant Juan Rico recommends a couple of field promotions be performed on the way back to base, to fill out his platoon. Juan's captain explains why you never promote on the way back to base (higher headquarters will grab them).
** Earlier, Rico is breveted from lance-corporal/Assistant Squad leader to sergeant/Assistant Section Leader (skipping corporal/squad leader). The officer in charge feels that it makes more sense to leave as many squads as possible with their squad leaders, since the MI mostly operates by squad, and things have been rough lately.
** A subversion happens when Rico is at OCS. We find out one of his fellow officer candidates received a battlefield commission as a 1st Lieutenant some time prior, and had since been promoted to ''Captain''. (In case anyone didn't realize it, graduates of OCS start out with the rank of 2nd Lieutenant, so Rico's classmate would actually be ''demoted'' after graduating.) The reason he's attending OCS is to become an officer "properly" - as a battlefield commissioned officer (with no higher education), his chances of rising higher than Captain are very small. With Academy education and field command experience, his prospects are suddenly very good indeed.
* In Creator/LoisMcMasterBujold's ''[[Literature/VorkosiganSaga The Warrior's Apprenctice]]'', Miles Vorkosigan accidentally finds himself Admiral of a fleet, during which he puts all his original companions in high positions whether they can handle it or not. In ''The Vor Game'', he assigns his personal bodyguard to the emperor; when the man says he hasn't been trained for it, Miles can only say that it's a common problem in the situation.
* In David Feintuch's 1994 science fiction novel novel ''[[Literature/SeafortSaga Midshipman's Hope]],'' as the last surviving ship's officer dies of melanoma, the eponymous midshipman is promoted to command.
* ''Literature/OldMansWar'' by John Scalzi, where the main character is promoted three times. First, he moves from private to corporal after his boss is killed. He jumps all the way to Lieutenant for reasons that are essentially hand-waved (ostensibly to do a liason mission). Finally, after performing heroically in this mission, he gets another promotion to Captain. [[LampShadeHanging Lampshaded]] when the character notes that if anyone noticed that he'd gone from corporal to captain in a month, no one said anything. Unlike his prototype, Heinlein, Scalzi's world doesn't include specialized officer training or other qualifications.
* In Creator/DanAbnett's TabletopGame/{{Warhammer 40000}} Literature/GauntsGhosts novel ''Ghostmaker'', Gaunt has just gotten a large portion of a regiment off Tanith before its destruction. When his men tell him that the officers were all on planet and dead, he appoints the man who told him (and did most of the talking in the meeting) as Colonel, and the man who came with him as Major, and told them to appoint appropriate junior officers.
** He does this partly because those two men were chosen by the other soldiers to approach him, and so clearly command some sort of respect among their peers. He's also well aware that at least one of them hates his guts and wants to "keep his enemies closer."
** Also, in the series's backstory, the current Warmaster Macaroth was promoted to his position by Warmaster Slaydo during the liberation of Balhaut. Slaydo, who was mortally wounded, specifically named Macaroth, who was a relative unknown, as his successor. Though nobody is exactly sure why he chose Macaroth, many scholars believe that Slaydo did so in order to prevent the other senior officers from fighting over his position.
* In William King's TabletopGame/{{Warhammer 40000}} Literature/SpaceWolf novel ''Ragnar's Claw'', after Ragnar [[YouAreInCommandNow gives orders to Space Marines who, he later realizes, included his commander]], and his sergeant was brought down, he is put in the sergeant's place.
** In Lee Lightner's ''Wolf's Honour'', when Sven reports to Mikal that their pack's leader is down, Mikal asks who should be in charge; Sven says, by rights, it should be Freyr, but Mikal overrules on the grounds that Freyr is not there, reporting to him, and puts Sven, who is, in charge.
* In Creator/JamesSwallow's TabletopGame/{{Warhammer 40000}} Literature/BloodAngels novel ''Deus Encarmine'', the grief-stricken Rafen, seeing Sergeant Koris, his mentor, brought down by the Black Rage, is ordered to take Koris's place in command of the squad.
** In ''Deus Sanguinius'', at the end, he is offered a field promotion to a captaincy as a reward. He declines it as he has not earned it.
* In Creator/JamesSwallow's TabletopGame/{{Warhammer 40000}} Sisters of Battle novel ''Hammer & Anvil'' Sister Imogen dies during her squad's infiltration of the Necron crypt, her last words to Miriya were to complete the mission, essentially making her a squad leader (again). This is despite the former's distrust and dislike for the latter due to the events of the previous book. Similarly, Verity is told by the convent's canonness that she is now a Sister Militant, no longer a Hospitaller, as the convent is assaulted by a massive Necron force, and is given a master-crafted bolt pistol to start her off.
* Literature/{{Sharpe}} has lived this trope, fighting his way up. By the end of ''Waterloo'' he's passing out promotions like candy (there are a LOT of vacancies).
** In ''Sharpe's Rifles'', he field promotes Harper to Sergeant.
* Numerous characters in Creator/JohnRingo's ''Literature/PrinceRoger'' series. In the fourth book, only twelve survivors remain from the entire Empress' Own Regiment, and the senior (a company sergeant major) is promoted all the way to full Colonel in one jump to fill the obvious gap. Prince Roger himself, in the first book, is [[RoyalBrat a callow youth]] in severe need of discipline and training. So his bodyguard CO, a captain, field demotes him to second lieutenant (As a member of the royal family, he is technically a Colonel of The Empress' Own) and hands him a platoon. The captain does this partly because he needs someone to command the platoon, but mostly so he can gleefully watch the platoon sergeant's stunned reaction. It also has the added advantage of keeping Rodger safer by giving him a fixed position. Yes, putting him directly on the firing line is safer than letting him [[LeeroyJenkins decide what to do on his own]].
* The third book of Jim Butcher's ''Literature/CodexAlera'' has this. [[spoiler:Tavi]]'s jump from Third Subtribune Logistica (junior supply officer) to Captain of a Legion is more of of a YouAreInCommandNow but he starts handing out field promotions left, right and centre to fill holes in the legion's absolutely shattered command structure. The fourth book reveals that most of them stick too.
* In ''[[Literature/TheBelgariad Polgara the Sorceress]]'', Sergeant Torgun has to go a little beyond his orders to head off trouble at one point. When he reports:
-->'''Torgun''': ...Is it all right that I did that, my Lord?\\
'''Kamion''': Perfectly all right, Captain.\\
'''Torgun''': Ah -- I'm only a sergeant, my Lord!\\
'''Kamion''': Not anymore, you aren't.
* ''Literature/{{Discworld}}''
** In ''Discworld/MonstrousRegiment'', Maladict gets a field promotion to corporal.
** ''Discworld/MenAtArms'' features a number of field promotions in the A-M City Watch, some of which are actually official. (As recruitment into the Citizen's Milita goes critical, some people are promoted by officers who don't strictly have the right to do so, and others are under the impression you ''decide'' what your rank is, based on how many other people you've recruited.)
** And in ''Discworld/GoingPostal'', Moist tries to cajole elderly Junior Postman Tolliver Groat into telling him about the secrets of the Ankh-Morpork Post Office with an implied promotion: "You tell me right now, ''Senior'' Postman Groat!" Later, Devious Collabone finds himself field promoted from university researcher, to doctor, and then again to professor, in the span of a few minutes. Mainly because a civilian tried to gainsay him in the presence of Unseen University's Archchancellor, Mustrum Ridcully, a firm believer in Retaliation By Promotion.
** Sergeant-At-Arms John Keel (actually a time-lost Sam Vimes) in ''Discworld/NightWatch'' promotes Corporal Colon to sergeant during the Seige of Treacle Mine Road. In the opening scene, the present-day Sergeant Colon mentions this, adding that he was made a corporal again once the crisis was over.
* In Anthony Reynolds's TabletopGame/{{Warhammer 40000}} novel ''Dark Apostle'', Captain Loren is promoted to ''acting'' colonel. The adjective is emphasised to lend weight to the reason: there is no one else.
* In Creator/TamoraPierce's ''Squire'', from the ''Literature/ProtectorOfTheSmall'' series, Keladry is serving as squire to a knight who is also commander of the King's Own, a military force. She herself is given a field promotion of sorts -- put in charge of a squad despite not technically being a member of the Own, because the higher-ups know its actual leader can't handle the job. What they end up fighting is a giant robot insect thing PoweredByAForsakenChild, and it turns out that the best way to kill it is to trap its head and open a hole in it, so the child's spirit can leave. She gives a field promotion to the soldier who figures this out, even though earlier he'd almost started a mutiny over her being put in command at all.
* In Joe Haldeman's ''Literature/TheForeverWar'', Mandella starts as a private, and ends the war as a major commanding his own ground force. Not because he's particularly suited for command, but because he's adaptable, and it looks odd for someone who's been in the military for 500 years not to be an officer.
* ''[[Literature/TrailOfGlory 1812: The Rivers of War]]'' by Creator/EricFlint has a number of these. In one case 21 year old Captain Sam Houston (bumped up from Ensign by General Andrew Jackson for his heroism in the [[http://en.wikipedia.org/wiki/Battle_of_Horseshoe_Bend Battle of Horseshoe Bend]]) and 32 year old Lieutenant Patrick Driscol (more-or-less browbeaten into accepting a commission after losing his arm during the [[http://en.wikipedia.org/wiki/Battle_of_Chippawa Battle of the Chippawa]]) both end up in Washington D.C. in time to rally several hundred leaderless troops (more or less against orders) and defend the Capitol from [[http://en.wikipedia.org/wiki/Burning_of_Washington invading British troops]]. Not long afterwards ''Colonel'' Houston and his XO ''Major'' Driscol were dispatched at the head of the First Capitol Volunteers to reenforce New Orleans.
** The funny thing is that the person who recommended them for that field promotion was the commander of the British forces - being defeated by a Colonel is far less embarrassing for a Major General than being defeated by a brevet Captain who was only there by chance.
* In Creator/AndreNorton's ''[[Literature/{{Warlock}} Storm Over Warlock]]'', at the end, Shan Lantee finds he's been given a cadet uniform at the end, although he's a casual laborer -- and then finds that he's been appointed cadet.
* Shortly after the French landings in Britain at the beginning of ''[[Literature/{{Temeraire}} Victory of Eagles]]'', the high command got word of local militia west of London defeating several french foraging units (by some accounts even making use of unharnessed dragons that had wandered from breeding grounds in that direction) and sent a messenger with a battlefield commission of Colonel for whoever was in charge. Temeraire accepts with alacrity, to the suprise of all humans involved.
* Happens to both the Americans and the Soviets in Creator/TomClancy's ''Literature/RedStormRising'': amongst the viewpoint characters, Sergeant Terry Mackall gets promoted twice, after his lieutenant and then his unit XO were killed in action, while FourStarBadass Pavel Alekseyev--the main Soviet POV character--receives a series of promotions from senior aide of CINC-Southwest to essentially commander of Soviet forces in Europe (as the situation grew more and more desperate, the Politburo began taking a progressively [[YouHaveFailedMe Vaderesque approach]] to its commanders). Also {{deconstructed}} somewhat, when discussing the state of the Soviet Army. Since NATO doctrine was to go for the unit commanders first, by mid-war many of the leading Soviet formations were led by junior officers who were field-promoted out of necessity--thus, captains leading battalions, majors leading regiments, and colonels leading entire divisions were not uncommon. The attrition rate on the officer corps had a very serious effect on the Soviet war effort, since the junior officers were almost always inexperienced men.
** Bob Toland, a Navy Reservist intelligence officer, gets breveted (or "frocked", as the Navy calls it) to Commander, to give him a little extra clout when speaking to the ''USS Nimitz'''s officers. It's noted that frocking confers all the responsibilities of the rank, with none of the pay.
* In Creator/JackCampbell's ''Literature/TheLostFleet'', Geary mostly just puts the officers in charge of ships, but some get promoted as well.
* In Creator/JackCampbell's ''[[Literature/TheLostStars Lost Stars]]'' novel ''Tarnished Knight'', Iceni promotes both Marphissa and Kontos.
* Happens everywhere in ''Literature/TheThinRedLine'', the most prominent example being two [=NCOs=]([[spoiler:John Bell and "Skinny" Culn]]) who get a commission.
* Firestar did this when Whitestorm, the [=ThunderClan=] deputy, died during the final battle of the first ''Literature/WarriorCats'' series, naming Graystripe deputy rather than waiting to hold the usually performed ceremony.
* In ''Literature/TheWayOfKings'', Kaladin saves an army from an ambush partly by doing this. [[BavarianFireDrill Note that as a slave, he has less authority than the horses]].
-->"You’re promoted," Kaladin said. "If anyone asks, you’ve been given a field commission as commander of the rear guard. If anyone claims to outrank you, send them to me."\\
The man started. "Promoted...Who are you? Can you do that?"\\
"Someone needs to."
* In ''[[ComicBook/XWingSeries X-Wing: Solo Command]]'' Wedge gives "Face" Loran a field promotion to brevet captain because Wedge decided to retake command of Rogue Squadron, and Face's previous rank of lieutenant is too junior for him to command Wraith Squadron. By the end of the book, the rank is made permanent.
* In the epilogue of ''Literature/TheFlightEngineer: The Independent Command'' General Scaragoglu gives Chief Petty Officer Paddy Casey a field commission as a favor to Commander Raeder, so that Casey can legally propose to his officer girlfriend.
* How {{Literature/Kydd}} is elevated to the quarterdeck. To elaborate, his commanding officer, Lieutenant Monckton, was knocked unconscious by the passing of a cannonball during the [[http://en.wikipedia.org/wiki/Battle_of_Camperdown Battle of Camperdown]], forcing Kydd to take command of his division.
[[/folder]]

[[folder:Live Action TV]]
* ''Series/TheBill'': In a law enforcement capacity, Sergeant Dale Smith has been Acting Inspector on a number of occasions, while other characters have been Acting Sergeants at times.
** Sam Nixon spent much of her earlier time as Acting Detective Inspector, but now has the rank permanently.
* On ''Series/{{Community}}'' the first appearance of Officer Cackowski, he's a mere Greendale security guard. A couple episodes later (and in all subsequent appearances), he's a local police officer.
** Chang gets a field promotion to chief of campus security after the current chief has enough of the insanity and quits. The Dean gives Chang the position because he is the only security guard left. The college is broke and all the other guards quit when they are told that in lieu of pay they can attend classes for free.
* A darkly comedic version happens in the first episode of ''{{Firefly}}''. A soldier named Baker is trying to call in air support, but requires a lieutenant's code. Mal rips the rank insignia off a dead lieutenant and gives it to Baker, congratulating him on his promotion. This probably wasn't legitimate since Mal was only a sergeant but the point is moot since the war would basically end a few minutes later.
* ''Series/{{Frasier}}'': A cook is promoted to chef during a party, after the original one had enough of Frasier's and Niles's contradictory micromanagement.
* This happens to Rimmer in ''Series/RedDwarf'' inheriting the title of "Commander Arnold 'Ace' Rimmer" from an alternate version of himself, once that version dies.
* ''Series/StarTrekDeepSpaceNine'' featured this in the backstory for General Martok. He was originally barred from being an officer because his family was not from a noble line. This left him unable to even enlist as a soldier, but he eventually earned a battlefield promotion aboard a civilian ship and rose through the military ranks.
** Likewise Nog still a cadet at Starfleet Academy when the Dominion War broke and he was promoted to Ensign.
** Deconstructed and taken to the logical extreme in the episode ''Valiant'' in which all the actual officers on a training ship trapped behind enemy lines died, the captain field promoted a cadet to acting captain just before dying and the acting captain field commissioned all the other cadets into officer positions. The crew was shown to be talented but not conditioned for war and not experienced enough to plan for contingencies.
* ''Series/StarTrekTheNextGeneration'': Picard gives [[CreatorsPet Wesley Crusher]] a field promotion from an acting ensign to a full fledged ensign, but not for a lack of officers. Picard wants to reward him for passing up his transport to Starfleet Academy in order to help rescue Riker and the Trois.
** And in the Season 4 opener. Picard is [[spoiler:assimilated by the Borg. Riker, who has just refused a third potential command, is field-promoted to Captain in his place.]]
** In ''Disaster'' Picard is stuck in a failing turbolift with three children, whom he makes officers to prevent them from panicking. They promptly [[NoOneGetsLeftBehind mutiny]] when he orders them to leave him behind.
*** [[CrowningMomentOfFunny The episode ends with both Riker and the 12-year-old first-officer responding "Yes, Captain" in unison when he addresses an order to "Number 1"]]
* ''Series/StarTrekVoyager''.
** B'Elanna Torres is made Starfleet lieutenant on Captain Janeway's authority (despite being a member of a rebel group known as the Maquis) as her skills in engineering mean she needs to be made chief engineer.
** Chakotay, another Maquis and a former Starfleet officer, is given his Lieutenant Commander rank back (and later promoted to Commander) and her first officer. Combined with his being a Maquis captain, he ends up as something of a double subversion.
** Tom Paris, a legitimate but disgraced Starfleet lieutenant, was reinstated. Later in the series, he got demoted for disobeying orders, and promoted later on.
** Tuvok, who was serving with the Maquis as a double-agent, was reinstated to his Starfleet rank of Lieutenant, and was later promoted to Lieutenant Commander; however, this was treated as a standard promotion.
** And poor Harry Kim gets to be the aversion, despite seven years of harrowing and dangerous missions in the Delta Quadrant and endless night watches, remaining an Ensign all the way to end of the series (then again, it's not as if anybody else got promoted past their initial commission either). It's continually suggested that he gets fast-tracked up the ranks once he's back home and made captain in less than ten years.
** And then there's The Doctor, who gets promoted from "supplemental diagnostic tool" to Chief Medical Officer.

[[folder:Video Games]]
* An Earthborn [[Franchise/MassEffect Shepard]] who according to Cerberus grew up as an orphan on Earth with no formal education. He/she enlisted in the Systems Alliance Military as a marine when he/she turned 18 starting the bottom rank of [[NewMeat Private 2nd Class]]. 10 years later, he/she is now a N7 (Special Forces) and a commissioned alliance officer with the rank of [[MajorlyAwesome Lieutenant Commander]].
* After the leader of his team [[StealthMentor defects to the enemy]], [[TheDeterminator Kyosuke Nanbu]] of ''VideoGame/SuperRobotWars OriginalGeneration'' is [[YouAreInCommandNow temporarily made into acting leader.]] [[spoiler:When his next superior, Ingram Prisken reveals himself as TheMole, he is given a field promotion to Lieutenant and official battle commander by {{The Captain}}s of the {{Cool Ship}}s, the Hagane and the Hiryu Custom.]]
* After the events of ''VideoGame/CallOfDuty 4: VideoGame/ModernWarfare'', the player character gets promoted all the way from SAS Sergeant to Captain in five years.
** That's not too unusual. A rank soldier in the British Army can recive a commission as a "Late Entry" officer (as opposed to a "Direct Entry" officer who went through Sandhurst). From there it is fairly realistic to go from 2nd Lieutenant to Captain in five years.
* ''VideoGame/GearsOfWar'' has this happen to protagonist Marcus Fenix via radio after Kim gets [[FamilyUnfriendlyDeath run through]] [[MadeOfIron by RAAM.]]
* [[PlayerCharacter The Force Commander]] in ''DawnOfWar II'' is a rather young SpaceMarine who has never met the Chapter Master, yet he has his rank because the Blood Ravens had their manpower seriously depleted because of the Kaurava Campaign (which Cyrus doesn't want to speak of). Thaddeus is also on the young side for a Sergeant and it shows, he's naive about many things and his fellow sergeants point it all out for him.
* During ''VideoGame/NeverwinterNights2'' the player is promoted from squire to knight in quick succession. When one of the other knight objects he is reminded that he was knighted in the mud surrounded by an army of orcs.
** The reason this may not make much sense is because the objection was to lack of a suitable ceremony, not the rapid promotion.
* The player character, John Cooke, in ''[[{{Videogame/Battlezone1998}} Battlezone II]]'' receives several field promotions by the local GeneralRipper, as their task force is totally separated from Earth's chain of command. When the player [[spoiler: kills [[DefectorFromDecadence Major Manson]], he is promoted to [[KlingonPromotion Major]]]].

* In ''Webcomic/AmericanBeauty'', [[http://www.ambarb.com/?p=261 Two Tanks Omen promotes a junior to number two, and orders him to kill his predecessor.]]
* Karcharoth of ''CryHavoc'' is promoted from Sergeant to Assault Sergeant Major in a month after his lieutenant is KIA and a replacement is not found.
* ''Webcomic/GirlGenius'':
** When Gil [[spoiler:destroys the attacking Clank Army with a lightning rod,]] the [[http://www.girlgeniusonline.com/comic.php?date=20071207 following exchange takes place:]]
--->'''Gil:''' All I want is your commander.\\
'''Mook:''' [[spoiler: You hit him with lightning.]]\\
'''Gil:''' Ah. Second in Command?\\
'''Mook:''' Him, too.\\
'''Gil:''' ...Third?\\
'''Mook:''' [[spoiler: He was in the second machine.]]\\
'''Gil:''' ''[sigh]'' Fourth?\\
'''Mook:''' [[spoiler:''[pulls out a knife]'' THAT WOULD BE ''ME'', MADBOY!]]\\
'''[THOK!]'''\\
'''Dimo:''' Hoy! So, who ''else'' vants to be '''''promoted'''''?
** [[spoiler:Ironically given his quote above, Dimo himself was promoted to one of the Jäger generals during a later TimeSkip.]]
* ''Webcomic/SchlockMercenary'':
** Early on, when Schlock helped the company reclaim the ship from food-service commandos.
--->'''Kevyn:''' I think that the general alarm has distracted the guards.\\
'''Tagon:''' We have the element of surprise! Schlock, you are a ''genius!'' I'm promoting you to Sergeant, on the spot!\\
'''Schlock:''' Ummmm, I think the alarm might have been pulled by someone who saw me. I have no plan. This was an accident.\\
''[beat]''\\
'''Tagon:''' Okay, then. You can be a Corporal.
** Captain Tagon's father complains that "when I was your age, I was already a colonel." Tagon retorts that there was a war going on back then, and half of high command got nuked from orbit.
** And then [[spoiler: there was a mass nanite attack, and Tagon Sr. was suddenly a general.]]

* One of the commanders of a Philippine resistance group against the Japanese during UsefulNotes/WorldWarII started out as a US Army lieutenant. By the end of the war, he had been promoted to major (via radio messages) but was effectively in charge of far more men than a major would normally command, spread throughout the islands. To facilitate this, he field/brevet-promoted men to be in charge of various cells, areas and islands. Since some of these were commanding hundreds or even thousands of irregular troops, he gave out acting promotions higher even than his own substantive rank of major. Luckily, General [=MacArthur=] was understanding.
* Averted in militaries that don't have the rigid correspondence between rank and position, such as Russian Army in all its instances. There, the officer in command simply stays in his rank and continues to command his unit until the wheels of military bureaucracy turns and he gets actual promotion. During WWII there were Red Army majors that commanded ''divisions''. Yeah, right, ''majors'', not major-''generals''. If a division was commanded by a colonel, they didn't even bother to promote him.
* George Armstrong Custer was breveted from Lieutenant to Brigadier General during the Civil War, though would [[TooDumbToLive end his career]] as a Colonel.
** This happened a lot in the Civil War, because the Union Army was vastly larger than the Regular US Army before and after the war. Many career officers who lived through the war held high brevet rank that disappeared in 1865. (Similar to the AUS example below.)
* Creator/AudieMurphy started as an [[ChildSoldiers underaged]] private, and was field promoted to Sergeant and later Lieutenant in a combination of his heroic actions and YouAreInCommandNow.
* In UsefulNotes/WorldWarII, [[Series/BandOfBrothers Dick Winters]] started as a 2nd lieutenant. By the end of the war, he was ''Major'' Dick Winters. At least one of his promotions was a field promotion (1st Lieutenant to Captain).
* A variation on this trope is the [[https://secure.wikimedia.org/wikipedia/en/wiki/Army_of_the_United_States Army of the United States]], the conscript (read: draft) force of the United States. When activated (thus far, it has only happened in UsefulNotes/WorldWarII, UsefulNotes/TheKoreanWar, and UsefulNotes/TheVietnamWar), many of the officers are initially drawn from the regular Army and the Reserves, where they receive promotions to deal with the increased number of men they will be leading. Once the war ends, and the AUS is stood down, the officers go back to their previous jobs... and their previous ranks, since the Army of the United States is a separate organization from the Regular Army and the Army Reserves. [[note]]Of course, depending on how long they were serving in the AUS, they may have received promotions in the Regular Army anyways, though not necessarily to the level where they served in the AUS).[[/note]]
* Though this is not technically a field promotion, Nathaniel Green was promoted from private directly to the rank of general (GENERAL) during the Revolutionary War. It makes sense then that he had several failures in this new position before he actually started to achieve victories.
* Peter Radcliffe, Regimental Sergeant-Major of the SAS during Operation Desert Storm, was promoted from RSM all the way to Major in one go in recognition of his actions in commanding a large SAS taskforce operating behind Iraqi lines. Slightly unusual in that the formal promotion didn't actually happen until some time ''after'' he ended up in charge of said taskforce. It was the first time in British military history that an officer was ''formally'' relieved of duty by an enlisted man, which tells you everything you need to know about said officer's competence.
* JimmyStewart joined the USAAF and started as a private, but because of his education and expert flying skills and experience, he became a pilot and eventually reached the rank of full Colonel, one of only four men to do so during the war. He was promoted to Brigadier General by RichardNixon.
* UsefulNotes/WorldWarII, the German army at Stalingrad deep in the USSR was completely surrounded and without ammunition or food. Rather than grant permission to surrender, [[AdolfHitler Hitler]] promoted (by radio) a generous amount of officers to higher ranks to boost their morale, including the commander General Paulus to rank of Field Marshal (the highest military rank). No Field Marshal in German military history to that point had ever surrendered: the promotion was a signal that Hitler wanted him to commit suicide rather than surrender. Paulus defied him and chose to surrender to the Soviets.
