For the future, could this be done?
Individual planes on the UNIT screen, if they are being jammed, have that notation next to them, as they should. But, if the plane is part on the GROUP SCREEN, the group does not have the JAMMED notation next to it. If you switch to the unit, you can verify, individually, that they are JAMMED. It would be nice if the GROUP SCREEN would indicate that, as well. Perhaps there is a reason as to why it isn't done? I don't know. In any case.....
The theory in a networked battle environment is that certain platforms can suffer adverse effects from countermeasures, but the group does not suffer a cumulative effect if each platform in the network group operates under a separate electronic signature whose information can be shared collectively.
Basically, opfor can't jam the collective combat intelligence of a group unless opfor has the capability to all possible source of feedback any aircraft could use to gather intelligence for the group function or stops the communications among the aircraft so they can't share individual platform intelligence in real time.
