Which weapon is a heavy machine gun used by Marines for long-range sustained fire?

• A. M16A4 rifle
• B. M2 .50 caliber heavy machine gun
• C. M249 SAW
• D. M9 pistol

Answer: (B)

Long-range sustained fire is the hallmark of a heavy machine gun. The Marines rely on the M2 .50 caliber heavy machine gun for this role. It’s a belt-fed, crew-served weapon chambered in .50 BMG, designed to stay on target at extended distances and deliver continuous fire when mounted on a tripod or vehicle. This setup allows effective suppression and engagement of targets far beyond the reach of standard rifles or lighter machine guns. The other options aren’t heavy machine guns: the M16A4 is an assault rifle for closer engagements; the M249 SAW is a light machine gun intended for squad-level suppressive fire but with a smaller caliber and shorter range; the M9 is a pistol, not a long-range suppressor. Therefore, the M2 .50 caliber heavy machine gun is the weapon described.
