Schwarzlose MG M.07/12

The M240 is the U.S. military designation for the Belgian-designed FN MAG (Mitrailleuse d'Appui General), a belt-fed, gas-operated, air-cooled general purpose machine gun chambered in 7.62x51mm NATO. Widely considered one of the finest GPMGs ever built, the M240 is renowned for its exceptional reliability under adverse conditions, robust construction, and sustained fire capability. It fires from an open bolt at a cyclic rate of 650 to 950 rounds per minute with an effective range exceeding 1,100 meters with the tripod mount. The M240 is deployed in multiple configurations including the M240B infantry variant with a buttstock and bipod, the M240C coaxial tank version, and the M240D helicopter door gun. The weapon traces its lineage to the original FN MAG designed by Ernest Vervier in the 1950s.

The PKM is a Soviet-designed 7.62×54mmR general-purpose machine gun. Modernized from the original PK design, it is lighter, more reliable, and widely regarded as one of the best GPMGs ever made. It is the standard squad and vehicle machine gun for Russian and many allied forces.

The M1919 Browning is an American .30-06 Springfield (later 7.62×51mm NATO) medium machine gun used extensively throughout World War II, Korea, and Vietnam. An air-cooled evolution of the water-cooled M1917, it served as the standard U.S. infantry, vehicle, and aircraft machine gun.
