 Squads can be broken up at any time to allow the player to use fewer squad members when walking about.This may give the player an advantage, for instance one man is harder to hit than four men standing closer together or it may be to keep a certain squad member safe because they possess and ability that is crucial to finished that particular mission and cannot be risked.Each squad member commands the same abilities as any of the others such as the ability to walk, swim, pilot vehicles and fire multiple weapons but the primary squad member is the only squadie that can also climb certain surfaces.
