The MG4 is a light machine gun featured in Medal of Honor: Warfighter. It was first seen with a camouflage and an Trijicon ACOG TA11MGO (Machine Gun Optic). The MG4 is a 5.56 mm belt-fed LMG produced by Heckler & Koch. It's a rather recent weapon, since it was developed in the 1990s and first presented to the public in 2001. It has been chosen to replace and/or complement the 7.62 mm MG3 machine gun.
