Is Jamming an ECM signal an active process that must be maintained like current Electronic Warfare counter Measures or is it more like an EMP that just turns off ECM?
In practice:
If my Talon activates ECM to block Target-Locks, then my opponent successfully Jams my ECM with his warden, is my ECM gone until next turn or would it be back if I immediately destroy the warden that jammed my ECM on my next activation during that turn?
