I had 2 NCO gunners in a bunker, snipers and zooks in a cam net further back, and a half track with hq attachments. AT wave 97, a v1 blitz ended all of that.
I said this before, but it off, so Ill say it again. when your partner is glitched and cant be revived, save and quit. Then when you continue the game, he/she will be back up again. Hope it helps. vote this up so others can see it.
