Corps to use more lethal ammo in Afghanistan
The Marine Corps is dropping its conventional 5.56mm ammunition in Afghanistan in favor of new deadlier, more accurate rifle rounds, and could field them at any time. The open-tipped rounds until now have been available only to Special Operations Command troops. The first 200,000 5.56mm Special Operations Science and Technology rounds are already downrange with Marine Expeditionary Brigade-Afghanistan, said the commander of Marine Corps Systems Command. Commonly known as “SOST” rounds, they were legally cleared for Marine use by the Pentagon in late January, according to Navy Department documents. SOCom developed the new rounds for use with the Special Operations Force Combat Assault Rifle, or SCAR, which needed a more accurate bullet because its short barrel, at 13.8 inches, is less than an inch shorter than the M4 carbine’s. Compared to the M855, SOST rounds also stay on target longer in open air and have increased stopping power through “consistent, rapid fragmentation which shortens the time required to cause incapacitation of enemy combatants,” according to Navy Department documents. “This round was really intended to be used in a weapon with a shorter barrel, their SCAR carbines,” the Marine Corps Systems Commander said. “But because of its blind-to-barrier performance, its accuracy improvements and its reduced muzzle flash, those are attractive things that make it also useful to general purpose forces like the Marine Corps and Army.”
