History Main / ImpededCommunication

* ''Film/OurManFlint'': After the GALAXY organization delivers its DoNotAdjustYourSet disarmament ultimatum to the nations of the world, they jam worldwide airwave communication (such as radio).

* ''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.
* ''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.)

* In ''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.

->''"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."''

->''What made the German panzers so terrifying in UsefulNotes/WorldWarTwo was not their heavy armor, their large guns, or their speed. In fact, the German tanks were generally mechanically inferior to their rivals. But the piece of equipment they had that their opponents lacked was a radio. Where the Allied tanks would have one radio per platoon, the Germans made sure each tank had a radio. This enabled them to demonstrate coordination beyond the ken of their opponents. So, from the opponents’ perspective, it seemed like the Germans were everywhere at once, finding every weak spot in the line, and driving deep behind the lines to sow chaos and terror.\\
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.''

* ''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.

* ''Film/OurManFlint''. After the GALAXY organization delivers its DoNotAdjustYourSet disarmament ultimatum to the nations of the world, they jam worldwide airwave communication (such as radio).
* ''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.

* ''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.
