Well, there is a certainly a bit of a problem with tac-aids here, but I guess we can figure out how exactly to do that and whether or not crouching is really necessary albeit unrealistic. Quote Luis
The fact that we crouch on a stack up its pretty realistic. Well not exacly realistic but its an idea... =P
Something like that was also a thought I had. The coverman should, if he covers the same or roughly the same direction as the pointman simply move a bit to the side so he can shoot past the pointman. This means, though, that the pointman can not quickly move to the side and shouldn't.
Our movement should now be something like ITS when they do the police line in which the guy behinds you stacks on your shoulder as you move.
