Jammer Pack

The  is one of the backpacks used in the game Tribes: Ascend. It is used by the Raider class and is an unlockable item.

The jammer is essentailly a mobile, shorter range Drop Jammer. Activating it shrouds you and any allies within the range in a white glow and disables the markers over your head(s) making it impossible for the enemy to identify your class and sometimes causing confusion since most people are so used to identifying players by their markers. You also cannot be spotted. The jammer will scramble any enemy infiltrator's stealth. Perhaps most importantly, you and friendlies under the effect of the jammer are un-targetable by enemy turrets which lets you take them out with impunity.
