I've watched some gameplay videos and I've seen that it's possible to play with 3rd person view. If this is supposed to be "realistic" game, how come it's possible to look over walls or around the corner even though your eyes and the whole body is behind that wall? The enemies can't see you but you can see them very clearly.
My suggestion is that the 3rd person view should be disabled, at least when you're not in a vehicle.
