Shield Guard is armed with extensive riot gear. These mercs can prove to be a formidable enemy. unlike previously seen elite mercenaries, shield guard have a helmet and visor requiring more than one bullet to the head to kill them. They notably are the mercenaries that are the close body guard of Crowe and Krieger that the player fights before they both die.
Shield guards at first wield M4 assault rifles but progressively they will begin to use the G36 then the OICW.
