Was browsing the game files and found 3 Uniforms, one for each faction, I am wondering what they may be used for but it may pertain to my disguises idea I had made a while back. Any insight into this?

They're enabled in deathmatch game mode and available as vests in the armory. They don't have any other effect but changing the visual appearance. Great for deathmatch as technically you all are in the same faction.
