How the heck am I supposed to stop an airstrike with electronic warfare for the “Air Defense” achievement?
The air strikes come in from behind the enemy deployment area. You have to have a spotting unit near there and hit the incoming fighter jets (they will have a red IFF icon) with an EMP. You need to be fast, and the target of the air strike has to be somewhere between halfway and all the way across the map otherwise the EMP won’t hit in time. Needless to say this is bloody difficult and damn near impossible to do in the heat of battle. It is possible to obtain this achievement in skirmish mode, though I’ve never been a huge advocate of boosting.
