Just watched Saving Private Ryan and noticed just how useful this could be in a game. Obviously the standard way you tell if it's an enemy is by listening to the sound of the weapon but I reckon it would be cool if when in a building you could have a key to make a callout for team mates. Anyone within range could then have a reply key where they respond to the callout.
This could help cut down on accidental team kills when clearing houses which we must all 'fess up to on numerous occasions.
Anyway, I just think it's a fairly cool idea though I don't know how realistic it would be for the Germans and Russians. I assume they had some sort of system for it seeing as they were fighting in the cramped, room-to-room situations in Stalingrad.
