As defined in Total Warfare, when using ECM to power Stealth Armor, "...the 'Mech suffers effects as if in the radius of an enemy ECM suite." I was wondering, though- if another unit came along and emitted an ECCM bubble, would that nullify the self-inflicted ECM effect of the stealth unit? Logically, it doesn't make much sense, but I'd nevertheless like to get official word on this if possible.
