ECM Effects

Defense Bonus: ECM's "defense against being hit" status effect does not stack, only the strongest effect present will be counted. This applies to both the personal protection and the aura (four 'mechs with Guardian ECM and one 'mech with Angel ECM all huddled together applies +2 defense to all in the bubble, not +5). If a mech is within the radius of both Angel ECM and Guardian ECM and is shot by a volley of both missiles and autocannons the +2 Defense against Missiles from the Guardian ECM will apply to the missile attacks while the +1 Defense against all attacks from the Angel ECM will apply to the Autocannon attacks. Note, Sanctuary ECM is an exception to this rule.

Sensor Lock Immunity: ECM provides immunity to the evasion reduction effect of Sensor Locks similarly to the first part of the Invisible Target Skill. It does not prevent the accuracy reduction or prevent a unit from being detected and targeted due to a sensor lock.

Standard ECM

Guardian ECM

The Guardian ECM Suite was introduced in 2597 by Johnston Industries of the Terran Hegemony. Designed to interfere with guided weaponry, targeting computers, and communication systems, the Guardian was typically used to shield allied units from such equipment by emitting a broad-band signal meant to confuse radar, infrared, ultraviolet, magscan and sonar sensors.

Notes:

  • ECM has a 150m radius aura which is shown by a white segmented ring around the equipped 'mech. Allies must be within that ring in order to share the +2 missile defense

Guardian ECM (C)

The Clans used the Guardian as the basis for their own ECM Suite, which was lighter and more compact than the Inner Sphere model but functioned identically. In the honor-bound fighting style of the Clans, the system did not see much use, but following their return to the Inner Sphere the Clans have since begun to outfit more machines with ECM systems.

Angel ECM

The Angel ECM Suite is an advanced version of the Guardian ECM Suite operating on a broader spectrum and greatly advances ECM technology on the battlefield. Development of the Angel began in the Draconis Combine shortly after the Battle of Luthien, but despite assistance from ComStar, cost overruns and internal problems within both powers kept it in its experimental stages for a long time and delayed its widespread deployment.

Sanctuary ECM

Given the Sanctuary's tendancy to use widespread wireless controlled drones in combat, the Sanctuary Worlds quickly learned a great deal about ECM technology, including how to harden drones against it. A side benefit is that they learned a lot about hardening their normal mechs and tanks even further against enemy ECM effects. The end result is this, the standard Sanctuary ECM equipment. While not as powerful as the best ECM the Inner Sphere can muster, Sanctuary ECM comes with the die befenfit of reinforcing nearby ECM fields instead of overriding them like Inner Sphere ECM does and Granting the carrying unit virtual immunity to enemy sensor locks.

Experimental ECM

Experimental EWAR Suite

Prototype Electronic Warfare component. Adds a defensive ECM field for the carrying unit and adds the Active Probe ability to unit's weapons panel. Active Probe is a triggered ability that uses the firing action and performs a Sensor Lock against all enemies within range. Unique gear for the Raven RVN-1X and the Cataphract CTF-0X, it is fixed gear and cannot be removed from the 'Mech.

Manufacturer: Achernar

Equipped Effects:

Critical Effects:

  • DESTROYED: Equipped effects disabled.

Notes:

  • There is no ECM radius on this unit, the defense against being hit is only for the equipped 'Mech

X-1 EW Equipment

Prototype Electronic Warfare component. Adds an ECM field that provides a passive defense against attacks. The EW Suite also adds the Active Probe ability to unit's weapons panel. Active Probe is a triggered ability that uses the firing action and performs a Sensor Lock against all enemies within range. Note: you can only equip one Prototype component on most 'Mechs. Unique gear for the Raven RVN-3X, It is fixed gear and cannot be removed from the 'Mech.

Anti-Missile ECM

Designed and integrated into the experimental Raven-4LX, the Anti-Missile ECM combines the circuitry of a Guardian ECM with a unique sensor scrabler that interfers with incoming missile targeting. The Anti-Missile ECM emits a special signal that actively scrambles incoming missile fire in an area around the unit, keeping the Raven-4LX and its allies safe under even the heaviest weapons fire. However, the effect proved prone to maintenance woes and remains experimental. Unique gear for the Raven RVN-4LX, it is fixed gear and cannot be removed from the 'Mech.

Manufacturer: Hellespont

  • +6 Missile Defense in a 150m radius
  • Blocks C3 bonuses for both allies and enemies in a 120m radius
