Yeah, but ambush units should be able to get forced off by vehicles or there won't be counterplay to that reward.
They have to lose faust.
Remember CoH1? Those Piat squads had camo just to ambush vehicles.
I am not entirely sure if falls mimic the same mechanic but i see that CoH2 vehicles have a design flaw, lighter vehicles have scouting abilities/stats (ideal to counter camos) but are vulnerable to fausts, but medium/heavies are designed towards combat and are useless to detect smaller squads hiding in camo.
Im just being lazy to ask but did track abilities (like the one on Zis or Su76) reveal camo units?
