The possibility (some scripting commands) to turn the current civilian/animal class dogs into attacking units, would be quite cool. To make them aggressive towards everybody or certain sides. Not much waypoint behaviour or something except "move". Something like zombies (in terms of handling/behaviour). When they see an hostile unit, they attack it. I'm not asking because of DayZ, but just for the default Arma gameplay. Would add some melee component (and the units themselves are already ingame). Further, armed forces use dogs, so it would not be that unrealistic as well.
