The Mobile Radar Jammer (MRJ) disrupts enemy radar functions, shutting down transmissions and display. The range of this unit allows it to hide a good distance away from the enemy base while other forces use the radar blackout to attack.
- Red Alert manual(src)

The radar jammer is a utility vehicle used by both sides involved in the Second World War.


Built around the frame of a mobile command center, it can jam the enemy radar using a white-noise generator. In order to do this, the vehicle has to come into the vicinity of the enemy structures.


Red Alert universe

The role of disabling the enemy's radar was passed on to the Allies' Spy during the Third World War and its second iteration. The Soviets decommissioned the vehicle entirely during this period.

Game unit

The vehicle is basically a treaded armored vehicle who house a portable radar jammer. The basis of the vehicle may be APC or Minelayer, as both are observed to have required mobility. The jamming equipment jams radar screen by creating a large "fog of war" around the vehicle. It only affects radar screens, as the actual vehicle is virtually unarmed and can still be observed with the naked eye. The vehicle did not seem very popular, since most commanders chose the Mobile gap generator instead, which has better covering value, regardless of the expense and the tier required. As such, the vehicle was clearly out of phase after the war.


  • During the Legacy Of Tesla mission in the Counterstrike expansion, this vehicle was used as the basis for Tesla Tanks. In that particular mission, the player is given six of them to start with, can not actually build any, as the tanks are still experimental. They were succeeded by the newer Tesla Tanks in the Aftermath expansion. There is a glitch which allowed the radar jammer to keep the Tesla weapon after the mission Legacy of Tesla has been aborted and a skirmish game is started. For this glitch to work, the Aftermath expansion should not be installed.
