9	->''"That means that the true counter to the form of rapid attack made possible by 'Doctrine: Mobility' is not some sort of novel weapon or armor. It’s the seemingly humble wide-spectrum communications jammer. If you can break the radios, the whole fast-moving apparatus collapses under its own weight into a confused mess. One with no other option than to engage in a frontal assault against the obvious strongpoints."''

12	All humans and animals rely on communication with others just to survive, let alone have a comfortable life. If this communication is sabotaged in any way, the results can be devastating for both sides of the party, simply because everyone wants to believe that their message went through unscathed and that the other person can and will respond. Nobody wants their letter to be stolen in the mail, nobody wants their call to be interrupted by a passing storm or cut wire, and nobody wants to be manipulated by someone else masquerading as their intended correspondent.
13
14	In this sort of situation, the communication isn't ruined by one of the parties themselves, like with PoorCommunicationKills; instead, it's ruined by an outside force, whether it be a freak act of nature, a being with malicious intent purposefully causing trouble, or even just the result of the chosen messenger running into trouble and being unable to deliver the message. Similarly, it can occur between two people and a third party, or one person attempting to get a message out to the entire world, only to be prevented.
15
16	In this way, this trope can count everything from inconvenient and spontaneous signal jams, to a malicious third-party getting in the way.
17
18	This trope has several subtropes:
19
20	[[index]]
21	* CellphonesAreUseless: A cellphone goes dead, making communication impossible.
22	* ConvenientlyInterruptedDocument: The discovery of information is prevented due to a document stopping at a bad time.
23	* CorruptedData: Crucial information is lost due to corruption.
24	* CutPhoneLines: Making sure that your target cannot call for help using the landline.
25	* GuardStationsTerminallyUnattended: The request for information is not fulfilled due to the guards being either dead or in the process of being made unalive.
26	* HisNameIs: Someone abruptly dies before they can reveal critical information.
27	* ICantHearYou: Hijinks with impeded communication.
28	* ImpededMessenger: The messenger fails to deliver the message.
29	* INeverGotAnyLetters: A character's messages to another are outright hidden by a third party.
30	* LostInTransmission: Technical difficulties result in a sent message being incomplete.
31	* ManipulativeEditing: Editing the original work so heavily the real message is lost.
32	* NeverSentAnyLetters: Someone sent letters pretending to be someone else.
33	* QuoteMine: Someone uses only portions of an original statement for their own benefit.
34	* RecordedSplicedConversation: Passing off a modified recording of an individual as genuine.
35	* SuddenLackOfSignal: The characters have ended up in a place where the external infrastructure necessary for their communications simply doesn't exist.
36	* TranslationWithAnAgenda: A translator changes or ignores the intended message, for their own benefit.
37	* TrollingTranslator: A translator mistranslates something for the lulz.
38	* TwistingTheWords: An originally innocent message is twisted to make the speaker look bad.
39	* VideoCallFail: A video call is affected by an external force, like poor wi-fi connection, which can impede an important message.
40	[[/index]]
41
42	However, while the act is more often than not malicious, it can sometimes be done by the protagonist in a desperate situation, and can even be portrayed as good if it's the villains affected by the communication struggle. In wartime scenarios, this can be necessary to give one side an advantage, as pragmatic as it may be. Finally, the result may be anything from wacky hijinks ensuing, to evoking a strong sense of isolation, and anything in-between.
43
44	Compare with ForgedMessage and TheRadioDiesFirst. Contrast PoorCommunicationKills, where the communication failure is due to the character's own flaws, rather than any outside influence. This can be invoked by tropes like FakeStatic and CuttingTheElectronicLeash, and can cause a SuspiciousMissedMessages scenario.
45
46	Finally, this is TruthInTelevision.
47	----
48	!!Examples:

50	[[foldercontrol]]
51
52	[[folder:Anime & Manga]]
53	* In ''Anime/GhostInTheShellStandAloneComplex'' episode "MARTIAL LAW", Section 9 steals a military helicopter to sneak into Dejima just as the Self Defense Forces impose a complete communications blackout. Chief Aramaki tries to convey a message just as it happens, but the last part of it gets cut off.
54	* In ''Manga/MyHeroAcademia'', 1-A's attempts to call for backup from U.A. are impeded by the machinations of the League of Villains, forcing 1-A to create an opportunity for Iida to run back to get TheCavalry.
55	[[/folder]]
56
57	[[folder:Comic Books]]
58	* Played with in the first issue of ''ComicBook/TheAvengers'', where the Teen Brigade attempt to radio the Fantastic Four to find the Hulk. Loki, who is attempting to pit Thor against the Hulk, uses magic to intercept and redirect the signal so Thor gets the message instead of the Fantastic Four. However, he messes up and the rest of the future Avengers (Iron Man, Ant Man, and Wasp) get the message as well. This directly creates The Avengers.
59	[[/folder]]
60
61	[[folder:Fan Works]]
62	* ''Fanfic/AbraxasHrodvitnon'': During the Many's attack on Castle Bravo and Godzilla, they cut the facility's power, preventing the Monarch cast inside from transmitting a warning to Yonaguni that the Many are sending one of their own to ambush [[AdaptationalHeroism Monster X]] on the island.
63	* ''Fanfic/DungeonKeeperAmi'': Ami is prevented from contacting her dungeon twice, when assaulting Salthalls, due to unexpected events reducing her magical abilities that she uses.
64	* ''[[https://archiveofourown.org/works/11800899/chapters/26618625 Hermione Granger, Demonologist]]'': Pansy Parkinson and her fellow bullies arrange for an older student to place silencing charms around the room where they corner Hermione to torment her, so that no one will hear her cry for help. It [[HoistByHisOwnPetard backfires on them]] when Hermione summons three powerful demons to turn the tables, and no one can hear ''their'' screams.
65	* ''Fanfic/MyHeroAcademiaUnchainedPredator'': VEGA intentionally cuts all communications between the HPSC and the JSDF in the end of Chapter 13, so as to prevent both the heroes and Japanese military from interfering in the Slayer's operation against the Steel Sabers on I-Island. By Chapter 22, VEGA restores communications between the two groups once the Slayer has gotten back into the sewers.
66	** During their campaign against the Sabers, VEGA also disables the Saber communication system and took control of I-Island's security to ensure that Nine couldn't alert them to their presence.
67	* ''Fanfic/{{Quizzical}}'': Quizzical's Notes communication spell is sometimes interrupted by large amounts of magical interference.
68	* ''Fanfic/TheReapingOfHatsuneMiku:'' The titular Music/{{Vocaloid}} has been rendered a CuteMute by the [[VideoGame/TheWorldEndsWithYou Reaper's Game]], and thus has to communicate by writing or typing. However, all her friends have suffered LaserGuidedAmnesia when they enter the Game with her, and if she tries to tell them about this, what she writes or types vanishes.
69	* ''Fanfic/ThroughTheLookingGlassMyNextLifeAsAVillainess'': In the world based on ''[[ShowWithinAShow Fortune Lover]]'', the Student Council is able to use a melody to allow a message to the canon world with instructions on how to respond. Unfortunately, the first to receive it is Game!Keith, who uses his magic to damage the rune on his side, blocking any form of contact [[IJustWantToBeLoved so he can stay with the kind Claes family of the other world]]. [[spoiler:However, there is an exception of two counterparts saying "I wish", which both Katarinas trigger]].
70	* ''Fanfic/TheUndying'': Flowey intercepts Alphys' call to Asgore about the murderous human and mimics the latter's voice so Alphys is none the wiser about the interference. The result is Alphys thinking she warned Asgore to prepare for the worst, Asgore not receiving any calls at all, and neither finding out what's actually going on until the danger has passed.
71	[[/folder]]
72
73	[[folder:Film -- Live-Action]]
74	* ''Film/DangerCloseTheBattleOfLongTan'': Both Eleven and Twelve Platoons have their radios knocked-out by enemy fire at various points; Private Akell has to run a spare up to Twelve Platoon. Back at base, the gunners find their switchboard temporarily disabled by a ''lightning strike''! (Historical note: the movie doesn't reference another strike that blew up the base latrines.)
75	* ''Film/GodzillaKingOfTheMonsters2019'': A passing mention by one of the eco-terrorists attacking Monarch's Antarctica base indicates that the base tried to launch an emergency beacon, but the terrorists cut them off in time.
76	* While traveling aboard ''Film/TheHindenburg1975'', the Countess plays cards with Napier and Pajetta, a pair of {{Card Sharp}}s who fleece the gullible on luxury cruises. The Countess quickly deduces their shenanigans, as well as their signal system. She discreetly edits these signals so that it's their wallets that get drained, rather than hers.
77	* ''Film/OurManFlint'': After the GALAXY organization delivers its DoNotAdjustYourSet disarmament ultimatum to the nations of the world, they jam worldwide airwave communication to prevent ZOWIE coordinating a response, but leave the phone lines open to ensure the world leaders can respond to their demands. Fortunately, Derek Flint seizes the GALAXY communications room and is able to transmit the coordinates of their IslandBase.
78	* ''Franchise/StarWars'':
79	** ''Film/ThePhantomMenace'': The Trade Federation jams the [=HoloNet=] prior to launching a ground invasion of the planet Naboo to prevent them from calling for help or warning anybody that the conflict has escalated. Queen Amidala and her court are in the middle of talking to Senator Palpatine when their connection to his office on Coruscant goes out; royal guard Captain Panaka assumes it's a glitch, but Governor Sio Bibble correctly guesses that the Trade Federation is preparing to attack.
80	** ''Film/ANewHope'': While pursuing a TIE fighter that just buzzed the ''Millennium Falcon'' and took a couple of potshots at them, Han Solo orders Chewbacca to jam its communications so that it can't alert the Empire to their location. Not that it matters: the TIE is [[LuredIntoATrap leading them right to the Death Star]].
81	* ''Film/SatansTriangle'': All the communication devices aboard the boat die around the time the deaths start. When Haig's radio also dies when he boards.
82	* ''Film/Saturn3'' has the captives Adam and Alex try to radio their distress to the MileLongShip that has come to check on them. However, their pleas are blocked by the mad robot Hector, who mimics their voices precisely, and tells the ship that all's well. The reply is a cheery "See you in six months," and TheCavalry departs none the wiser.
83	* Occurs twice in ''Film/TheTerminator'':
84	** Sarah Connor tries to issue a warning to her roommate Ginger by phone, but the killer robot has already liquidated her. Instead, Sarah's message to the answering machine reveals to the Terminator that he's killed the wrong target, and that Sarah Connor is at a downtown dance club.
85	** Sarah is hiding out at a motel, and decides to phone her mother (of course). Sarah is careful not to divulge her location, and leaves only a phone number. The terminator has already visited the mother's house and slaughtered the occupants, anticipating Sarah's call. It mimics the mother's voice, then calls back to learn where Sarah called from.
86	* ''Film/TheThing1982'': After the Antarctic research team discovers that they've been infiltrated by the title alien monster, they try to make contact with the outside world to warn them but can't because radio contact has been cut off by bad weather.
87	[[/folder]]
88
89	[[folder:Literature]]
90	* ''Literature/TheDemonBreed'': The Parahuans have the ability to jam human communicators. They've been gradually building up the interference for months, to make people think it's a natural phenomenon.
91	* ''Literature/TheExpanse'': This is a major issue throughout the series, due to the simple physics of reality. Light cannot travel faster than ''c'', and therefore neither can radio transmissions. So, ''light-delay'' must be accounted for when sending messages across the infinite void of space.
92	* The plot of ''Literature/{{Jackdaws}}'' centers around the use of a team of female saboteurs to destroy a German telephone exchange in occupied France shortly before D-Day. The reasoning behind targeting the exchange is that with the exchange destroyed, the German military would be either unable to coordinate troop movements to make a counterattack, or would be forced to use communications such as radio messages which could be more easily jammed or intercepted.
93	* ''Literature/TreeOfAeons'': As soon as Demon King Sabnoc arrives in the world, the [message] spell that enables near-realtime international and inter-continental communication stops working. This greatly disrupts the ability to coordinate any defence, and if people try to gather together so messages can be passed in other ways, then they're dense targets for the demons' artillery fire. The heroes are granted divine gifts to counteract the interference, by planting special broadcast towers to punch through, but those towers are priority artillery targets too.
94	* ''Literature/WeAllDiedAtBreakawayStation'' is a science fiction thriller that centers on a communication relay station that can route messages across interstellar distances in minutes rather than years. During the war between humans and the alien "Jillies," this station was ravaged, but is still functional. One last desperate stand is made at this relay station: the aliens aim to sunder it before Earth spies can transmit the location of the Jillie homeworld to Earth Command.
95	* ''Literature/XWingSeries'': PlayedForDrama in Tycho Celchu's backstory. A TIE pilot on the star destroyer ''Accuser'', he placed a [=HoloNet=] call to his family and fiancee on his birthday, only to have the signal go down during the call. His father was the CEO of Novacom, their home planet's largest [=HoloNet=] provider, so Tycho planned to give him some grief about the dropped call later. Unfortunately, their home planet happened to be Alderaan: he learned later he had just witnessed his family's death at the hands of the Empire. This prompted him to defect to the Rebel Alliance.
96	[[/folder]]
97
98	[[folder:Live-Action TV]]
99	* ''Series/TheBionicWoman'' episode "Doomsday Is Tomorrow" has an Air Force bomber ''en route'' to drop a cobalt bomb on the ElaborateUndergroundBase. A spotter for [=OSI=] sees Jaime Sommers emerge alive and well, and the recall code is issued to the bomber. The AIIsACrapshoot computer, however, wants the bomb dropped to create massive radioactive cloud. It beams the "404 = continue mission" code to the bomber, which is stronger than the "808 = abort and recall" code.
100	* ''Series/HouseOfAnubis'':
101	** Late in season 1, Alfie helps out the Sibuna gang by going into the cellar, while the others converse with him over walkie-talkie. He leaves the walkie behind and Jerome picks it up, pretending to be Alfie, which gets Alfie into trouble when the others think he's done and leaves while he's still down there. Jerome then uses this to manipulate Alfie into helping him.
102	** In season 3, Nina has disappeared without warning, and Fabian is a mess trying to figure out why. He discovers she sent Eddie a letter, and he goes to get it...only for this letter to have been written by Eddie and Jerome. Fabian realizes it immediately, and it only makes him get angrier, coming to the conclusion that Eddie and Nina had an affair over the summer. Eddie, however, wasn't doing it maliciously, but because he really ''lost'' the original letter.
103	** When Alfie notices that Amber has been getting calls from her dream fashion school, he tries at first to keep her away from her phone, so that she doesn't talk to them and get into said school. When he realizes how selfish this is, however, he tells her the truth.
104	* ''Series/QuantumLeap'': In "Revenge of the Evil Leaper," Ziggy is able to use a prison's electrical fence as a signal jammer to prevent Thames and Lothos from locking onto Alia's location.
105	* Occurs frequently on ''Franchise/StarTrek'' to keep the ''Enterprise'' from contacting Starfleet Command for back up, or to keep an away team from contacting the ship. Causes range from enemies stealing or destroying their communicators to aliens jamming their hailing frequencies to subspace interference from the NegativeSpaceWedgie of the week.
106	* ''Series/StrangerThings'': Owens leaves agents at the Byers house to prevent them from using their phone, or leaving the house to contact anyone. This means that the group still in Hawkins has no clue what is going on with them and Eleven and think they're ignoring calls while Hawkins is attacked, and that while the Byers are aware Hawkins is in danger again they don't know of the specific threats and attacks against their friends.
107	* ''Series/Zoey101'': In "Spring Breakup", the characters are cast as a reality show called "Gender Defenders", in which they're split into gendered teams and fighting for victory. Everything is going well until Chase steals Zoey's Tek-Mate, which unintentionally costs the girls a challenge- the others tried to contact Zoey, but with her Tek-Mate in Chase's hands, the messages never got to her. This sparked the conflict to become a ''lot'' more serious.
108	[[/folder]]
109
110	[[folder:Tabletop Game]]
111	* ''TabletopGame/BattleTech'': This trope is wielded by [[ImpartialPurposeDrivenFaction ComStar]] as a source of their power. As a MachineWorship religion [=ComStar=] jealously guards its monopoly on the construction, operation and upkeep of the SubspaceAnsible, and if [=ComStar=] decides a planet is going under FTL communications blackout, it will be. This is called "Interdiction" and is always announced publicly: A planet under Interdiction, nevermind a whole sector or nation, is dead meat before its enemies since they have no way of calling for help or reporting their status.
112	* ''TabletopGame/{{Paranoia}}:'' No matter the method of transmission, Friend Computer's vital and urgent orders to the players' Troubleshooter team are very often scrambled or distorted, either by Alpha Complex's ongoing physical deterioration, or deliberate sabotage by Commie Mutant Traitors.
113	[[/folder]]
114
115	[[folder:Video Games]]
116	* In ''VideoGame/AceCombat7SkiesUnknown'' both Osean and Erusean forces, at the height of the battle for Farbanti launch anti-satellite missiles hoping to cripple the other side at the same time not realizing that they had the same idea. This doesn't only take out military satellites but civilian ones as well due to the debris field it creates. This brings global communication to a halt and leads to massive infighting on the Usean continent. With Radical and Conservative Erusans, independent forces and the Oseans fighting each other ([[FriendOrFoe sometimes with themselves due to IFF not working]]) all sense of order is gone until the final battle when all of the latter join forces to fight the Radicals.
117	* Most large outposts and military installations in ''VideoGame/MetalGearSolidVThePhantomPain'' have communications equipment that the player can destroy (typically with explosives, though they can be shorted out in a more stealthy fashion with [[LethalJokeWeapon the Water Pistol]]). While this doesn't disable communication between units in the outpost, it prevents the outpost from raising the alert level of, or requesting reinforcements from, other nearby outposts if the player is spotted, at least until the equipment is repaired several in-game days later.
118	* ''VideoGame/Payday2'' allows players to bring ECM[[note]]Electronic Counter-Measure[[/note]] Jammers as part of their arsenal. Among their many useful features is that the Jammers block attempts from guards and civilians to raise the alarm by calling for backup or the police for the duration of their use (though it doesn't work for manual triggers, such as panic buttons during the Bank Heist missions, laser tripwires, or alarm-wired display cases).
119	* ''VideoGame/PAYDAY3'' brings back the ECM Jammers in a nerfed form - now, they merely slow down detection by cameras and extend the timer on pagers, instead of halting them completely.
120	* ''VideoGame/PresentableLiberty'': The main character is constantly being sent letters from people he cannot respond to, about problems he can't solve. Being stuck in a small room alone, the inability to reply underscores the unfortunate situation, while the characters on the outside are left to wonder if their letters are even being read at all.
121	* Units in ''VideoGame/SidMeiersAlphaCentauri'' can be equipped with the "Comm Jammer" ECM upgrade; this makes a unit have a more effective defense against a "mobile" land-based attacker (rovers and hovertanks).
122	[[/folder]]
123
124	[[folder:Web Video]]
125	* ''WebVideo/BenDrowned'': Jadusable's efforts to communicate his problem to people on the internet are disrupted by BEN, to the point where a good chunk of the posts are full of false information, and things Jadusable said being outright removed, just to mess with Jadusable's head and fool the audience.
126	* ''WebVideo/DontHugMeImScared'': In Episode 5, Red Guy keeps trying to contact Duck Guy, via the use of a telephone on set. However, every time the Duck Guy tries to answer, the antagonists of the episode take over, making it impossible for him to actually get the message. One such moment has the phone being turned into a sandwich in the next scene, confusing him and making it even harder to break free.
127	[[/folder]]
128
129	[[folder:Web Original]]
130	* On this blog discussing the technologies of ''VideoGame/SidMeiersAlphaCentauri'', the writer discusses just how important communication is in mobile warfare, and exactly why using a comm jammer on a mobile enemy could have such a devastating effect: https://paeantosmac.wordpress.com/2015/08/17/technology-advanced-subatomic-theory/
131	[[/folder]]
132
133	[[folder:Western Animation]]
134	* The ''WesternAnimation/SpongeBobSquarePants'' episode "Naughty Nautical Neighbors": [=SpongeBob=] and Patrick are communicating with bubbles that contain their voices. Squidward, whose house is between theirs, gets annoyed and secretly sabotages their messages by using his own bubbles that hurl insults at them. This causes Bob & Pat to hate each other for the episode.
135	[[/folder]]
136
137	[[folder:Real Life]]
138	* A major component of electronic warfare is attempting to disrupt, sabotage, or distort enemy communications.
139	* North Korea regularly jams South Korean propaganda broadcasts aimed at North Korea.
140	* While East Germany was unable to jam West German broadcasts in the same manner (doing so would cause West Berlin to also be jammed, resulting in all kinds of diplomatic incidents), they did change their TV standards to SECAM instead of the PAL system used elsewhere in Europe so that East German TV viewers would be unable to see West German broadcasts in color. In addition, there was a corner of southeastern East Germany that was beyond the transmission range of Western broadcasts; this area was called the "Valley of the Clueless"
141	* A major cause of the Franco-Prussian War was the infamous "Ems Dispatch", which was heavily edited by Otto Von Bismarck to inflame German opinion against France, and then mistranslated into French, causing France to declare war.
142	* Subverted with the infamous "Russian Woodpecker", a transmission from the Soviet Union which caused shortwave radio listeners to hear a series of tapping sounds over broadcasts, which was thought to be an example of this (others theorized even crazier possibilities, like it was being used for weather control and/or mind control); in reality, it was a long-range threat detection radar[[note]]Ie used to detect the launch of rockets, including ballistic missiles,[[/note]] whose usage happened to interfere with shortwave radio because of the wavelengths and frequencies used.
