On the heels of the Marine Corps’ desire for a new rifle for its infantrymen, the U.S. Army now says it is contemplating a dramatic switch in rifles. The service is considering going back to battle rifles—heavier rifles that can hit targets at longer ranges. The last time the Army fielded such a rifle was in the 1960s.
The story, broke by Soldier Systems Daily, says that U.S. Army troops feel they’re “in a street fight with a guy with longer arms.” That longer arm is the 7.62x54R cartridge, the cartridge used by the PK machine gun and Dragunov SVD sniper rifle. The PK squad machine gun is extremely common; it’s in use by the Taliban, the Islamic State, and most insurgent and terrorist groups worldwide. Longer and heavier than the 7.62×39-millimeter round used in the AK series of assault rifles, a PK with the 7.62x54R round has an effective range of 800 to 1,000 yards, versus only about 350 yards for an AK-47.
On the Army side, the maximum effective range of an M4 carbine against man-sized targets is about 500 yards, depending on the skill of the rifleman, and 700 yards for the M249 squad automatic weapon. Both fire the same cartridge. That leaves a dead zone of roughly 500 to 1,000 yards where the bulk of a nine person infantry squad can’t engage individual enemies. In a platoon of 40 soldiers, on average only about six soldiers armed with M249s, marksman rifles, and M240 machine guns have the range to engage an enemy in the dead zone.
