OK, this is a pretty tiny request, but I think it'd do wonders for game-play.

Instead of just showing images of weapons, vehicles and the likes in the HUD, add small labels like in Project Reality and Forgotten Hope:

It'd very likely to cause a reduction in the use of, say, "that big Imp fighter" instead of "the Assault Gunboat", making it easier to communicate with other players.
