Why Afghanistan Sent the U.S. Army Back to the M14

The M14 rifle was replaced by the M16 during the Vietnam War—but more than four decades later, modernized M14 rifles returned to combat. Adopted in 1957, the M14 was intended to replace several American infantry weapons at once. Its powerful 7.62×51mm NATO cartridge offered range and accuracy, but the rifle was heavy, its ammunition limited how many rounds soldiers could carry, and automatic fire was difficult to control. By 1970, the lighter M16 had become America’s standard infantry rifle worldwide. The M14 never completely disappeared. Accurized versions served as sniper rifles, competition weapons and specialist military systems. During the wars in Iraq and Afghanistan, existing M14 receivers were rebuilt with aluminum chassis, adjustable stocks, rails, bipods and modern optics. These Enhanced Battle Rifles gave designated marksmen greater reach without replacing the standard M4 or M16. This military history documentary explores why the M14’s original role failed, how it survived after Vietnam and why a Cold War rifle returned to the battlefield decades after its replacement. Watch until the end to discover why the M14 succeeded only after the military stopped asking it to serve every soldier.
