Medal of Honor: Warfighter[]

The Radar Jammer is a portable device that the player puts down in a set location and jams the radar of enemies, causing it to have its outline distorted and do not show friendlies and hostiles. It is also capable of disrupting enemy UAVs and prematurely detonating PDM 86s and Remote Charges. The Radar Jammer lasts until either destroyed or self-destructs after a set time.

Placing a Radar Jammer grants a "Place Jammer" bonus worth 20 points, and each time an enemy affected by the player's Radar Jammer is killed by a teammate, they will receive a "Jammer Kill Assist" bonus worth 5 points. Destroying an enemy Radar Jammer grants a "Destroy Jammer" bonus worth 20 points.
