Army Admits M4 Round is Under-Powered; Plans for a 7.62mm Alternative
Posted By: Matthew Cox May 26, 2017
The U.S. Army’s chief of staff told Congress the M4 Carbine’s 5.56mm round can’t penetrate modern enemy body armor plates and believes Infantry units need a more powerful rifle than the M4.
Gen. Mark Milley testified to the Senate Armed Services Committee that the service’s current M855A1 Enhanced Performance Round will not defeat enemy body armor plates similar to the U.S. military-issue rifle plates such as the Enhanced Small Arms Protective Insert, or ESAPI.
