Literally just replicate how it worked in coh2. In coh2 you could practically lose the squad before it could even take orders if you called it in right on top of the enemy
The game play cannot match Coh2 in any way or people will go "Coh3 is just a reskin man."
So:
Coh2 = Good, fun, solid mechanics that reward smart play and utilize the units correctly.
Coh3 = Lame, not fun, blob inf and vehicles with no penalty, no crush, nothing to reward thinking or APM.
People already call Coh3 a reskin and its nothing like Coh2.
Ironically, the only thing that can save Coh3 is making it more like Coh2. Rock meet hard place.
Add to this mess the fact they dont know what the &*&$ they are doing and you end at Relic is doomed to fail and go out of business. Thus the exodus of talent that started well before the game released.
These are the facts of the case and they are not in dispute.
