 CHAR: Sigint says that the enemies will not attack Snake from the  back when hes wearing the Cold War camo. Actually the enemies wont  attack from the front, they will attack from the back. This should  be obvious anyway, because this camo depicts the Soviet flag on the  front and the US flag on the back (the enemies are Russians). Also,  you get this camo by defeating Volgin by stamina depletion and  Volgin can only be attacked from the back.
