Meet the classic M4.
You Can't Beat It: The Army Uses This Powerful Rifle To Win Wars and Slay Enemies
The M4 still has its critics, including a retired major general, who have derided this descendant of the M16 as inadequate for modern ground forces. They point to the direct impingement gas operating system, which siphons off hot gases from burning gunpowder to chamber the next round, as guilty of fouling the inside of the rifle, increasing the likelihood of jams. They also deride the 5.56-millimeter round as having insufficient stopping power and believe the M4’s barrel is not thick enough to avoid overheating in sustained fire.
The U.S. Army is an armed force with a truly global reach. At any given time, America’s premier land power operates on several different continents simultaneously, from hot, dry deserts to humid jungles and sprawling cities. Its infantrymen carry a weapon whose lineage dates back to Vietnam but which has been constantly improved to become the weapon it is today. Rugged, simple and accurate, the M4 carbine is the standard infantry weapon of not just the Army but all of America’s ground forces.
