GECM
Overview & Gameplay
The Guardian Electronic Countermeasures (GECM) is notable for its discriminatory nature, able to scramble hostile electronics to reduce the Radar 'footprint' or signature of whatever its mounted to by 500m; while leaving friendly communications and targeting enhancers unaffected. If utilized by a pilot clever to respect their new, smaller radar footprint; it can enable them to push further into contested territory, relay detailed radar information to their team while being undetectable to the enemy.
GECM is found mounted on a variety of Mechs, Aerospace and Vehicles, typically to flesh out the units role as a scout, except in the case of the Thanatos mech' which has GECM hardmounted on all variants.
 The 500m reduction of a unit's radar signature is only while running Active Radar. It is still less effective than the 750m benefit of Passive Radar, but allows you to continue using your full compliment of active radar and other electronics.
 GECM increases the time it takes for an enemy to achieve target lock.
 Overheating will not be masked by GECM.
 Air GECM on Aerospace increases enemy lock on time (the best lock on protection of anything in MWLL), but does not change the user's radar signature. This means there is no reason to for Aerospace with GECM to use Passive Radar.
 VTOL GECM reduces the user's radar signature by 300m and increases enemy lock on time.

GECM The Guardian ECM Suite, originally introduced in 2597, is a powerful electronic warfare device able to disrupt a wide variety of sensors and detection equipment while leaving friendly units unaffected. Unfortunately the complex system was too difficult for the Great Houses to maintain during the Succession Wars, and it went extinct in the Inner Sphere in the year 2845, until it was eventually recovered by the Capellan Confederation in 3045.
