Spc. Ember M. Alt, 21, died Tuesday in Bagram of wounds sustained after enemy forces attacked her unit at the air base there.
According to a report from the Associated Press, the Taliban claimed responsibility for the deadly attack.
On Wednesday, Taliban spokesman Zabiullah Mujahid said the militants had fired two rockets into the base late Tuesday.
Alt was assigned to the 4th Infantry Division of Fort Carson, Colo.
Two other soldiers from Alt’s division, Spc. Robert W. Ellis, 21, of Kennewick, Wash., and Spc. William R. Moody, 30, of Burleson, Texas, also were killed in the attack.
Alt had been deployed to Afghanistan since Nov. 26 and was serving her first tour, according to Fort Carson spokesman, Staff Sgt. William Waller.
Alt joined the Army in May 2011 and had been at Fort Carson since November 2011, Waller said.
Alt, a wheeled-vehicle mechanic, had been awarded the Army Achievement Medal, National Defense Service Medal, Global War on Terrorism Service Medal and Army Service Ribbon.
Department of Defense officials identified Sgt. Justin R. Johnson, 25, of Hobe Sound, Fla., as the fourth soldier killed.
Johnson was with the 7th Sustainment Brigade in Fort Eustis, Va.
