Overview & Gameplay
The Guardian Electronic CounterMeasure Suite, or GECM, is an advanced electronic warfare suite that can be used to reduce the range at which enemy units can detect you on Radar, and can be mounted on both Mechs and Vehicles. In MWLL, this effect is represented by a unit's radar signature being reduced by 500 meters. This does not stack on top of a unit's reduced signature when in Passive Radar mode.
Regardless of GECM, the moment an asset overheats, they are equally visible to having no radar protection and running in Active Radar.
As of release 0.3.0, the GECM also increases the time it takes for an enemy to achieve target lock. This bonus does stack on top of the similar bonus given by running in Passive Radar mode.
