So, looking at the Squad Support Weapon rules, it struck me it would be handy if there was a way to bring more of the esoteric Electronic Warfare and sensor capabilities to lighter BA squads. Hence these ideas (both Inner Sphere):
Light IESS: Combines the ECM Suite, Improved Sensors, and Remote Sensor Dispenser capabilities into a package that provides ECM, Active Probe-like abilities, and three remote sensors per suit for 200kg for purposes of parsing out into a Squad Support Weapon. For construction, it requires each suit to leave 100 kg and 2 equipment spaces open (savings of 105 kg and 1 equipment slot per suit over installing all components individually for the cost of a halved number of remote sensors). When reduced to a single suit, a squad would lose its ECM Suite capability and any remaining remote sensors.
Heavy IESS: Combines the ECM Suite, Active Probe, Remote Sensor Dispenser, Laser Microphone and Search Light into a package that provides ECM, Active Probe, Laser Microphone and Search Light capabilities along with four remote sensors per suit for 400kg. For construction, it requires each suit to leave 200 kg and 4 equipment spaces open (savings of 200 kg and 2 equipment slots per suit over installing components individually for the cost of a reduced number of remote sensors). When reduced to a single suit, a squad equipped with this package would lose its Active Probe capability.
