This would be 2 different squads, one:
320th barrage ballon battlion, these would be a engineer squad being capable of building barrage ballon’s which would be able to weaken enemy airsupport
Ghost army: this squad would be able to create inflatable tanks and APCS, which would be capable of tricking enemy aircraft into firing upon them instead of actual enemy amour.
I would imagine that these would be a event squad.
