The FN SCAR heavy is the primary assualt rifle of the MNU security's special forces (extermination teams). The bullet size is 7.62mm x 51mm. It comes with three different barrel lengths: 330 mm (13.0 in) (SCAR-H Short), 400 mm (15.7 in) (SCAR-H Standard), 500 mm (19.7 in) (SCAR-H Long). The barrels are all interchangable providing the user with an easy-to-modify weapon for any sitiuation. The gun caliber can itself be changed to a 5.56mm X 45mm in ten minutes. This ability make the MNU security special forces detachments a very formidable foe. However the gun is expensive and is used by a small amount of the security forces. The majority use the Vektor CR-21 rifles with white stocks and what appear to be Leupold CQ/T optical sights.
