The rules for RISC Viral Jammer (IO:AE pp. 88-89) don't specifically state that it only effects enemy systems. Does this correctly imply that RISC Viral Jammer affects all valid target systems, friend and foe alike? Furthermore, does this cause RISC Viral Jammers to disrupt valid target systems installed within the user's unit as well (for instance, a unit with both Angel ECM and a Decoy Viral Jammer installed will end up disabling its own Angel ECM upon activating its VJ)?
