The U.S. soldier killed last week in an Afghanistan ambush was a member of the 7th Special Forces Group, the Pentagon said this weekend.

Sgt. 1st Class Allen C. Johnson, 31, was killed April 26 in Khanaqin when his patrol was attacked by an unknown number of fighters using small arms. Johnson, of Los Molinos, Calif., was a medic with the 1st Battalion, 7th Special Forces Group from Fort Bragg, N.C.

Johnson was posthumously awarded a Silver Star, a Bronze Star, Purple Heart, Meritorious Service Medal and the Combat Medical Badge, officials said.

According to media reports from his hometown, Johnson is survived by his wife — also in the Army — and three children. Staff Sgt. Eunice Johnson, assigned to the 519th Military Intelligence Battalion, was deployed to Iraq when notified of her husband’s death.

She left Iraq this week and accompanied her husband’s remains home to Fort Bragg from Germany, officials said.

Allen Johnson joined the Army in 1991 as an infantryman and served with the 75th Ranger Regiment, according to his military biography. In 1996, he changed his specialty to military corrections, and joined the Special Forces in 2000. He was assigned as a medical sergeant.

Johnson’s battalion deployed to Afghanistan last year and lost another member — Sgt. 1st Class Pedro Munoz — during a New Year’s Day raid in Herat, according to the Associated Press.

In a separate release this weekend, the Pentagon announced the name of a soldier who died of "non-combat related injuries" at Kandahar Airfield on April 23.

Pvt. Robert C. White III, 21, of Camden, N.J., was assigned to the 864th Engineer Battalion, 555th Maneuver Enhancement Brigade (Provisional), based at Fort Lewis, Wash.
