Army Chief of Staff Gen. Mark Milley told senators Thursday that the Army has developed a round that can penetrate 5.56 mm-resistant body armor.
During a Senate Armed Services Committee hearing on the Army’s budget request, Sen. Angus King, I-Maine, asked Milley how the Army was doing in developing a new rifle to replace the M4 and a more powerful round to replace the 5.56 mm bullet it fires.
“We think we have a solution,” Milley said. “We know we have developed a bullet that can penetrate these new plates.”
Milley said that rifles and body armor for U.S. troops are “critically important,” noting that 70 percent of U.S. casualties are borne by ground troops, mostly infantry and special operators conducting infantry-type missions.
