Well to be honest I don´t really think that this "use enemy uniform" thing will be used very often. I guess we will see it in one campaign mission and maybe in a few user made missions. And seriously, how are you going to get an enemy uniform without killing the guy wearing it (yes this is pretty unrealistic since the uniform would be full of blood)? I would like if BIS takes a different approach to that, it would be perfect if the player has to steal the uniform prior to wearing it. The player has to sneak into a camp and steal the uniform while the owner is showering, or the player spots a squad of enemys who have taken off their uniforms to go for a swim in the sea, he then has to take them out and gets a nice clean uniform without blood on it. Much more believable BIS!
