An airman out of Peterson Air Force Base was killed in Afghanistan, the Department of Defense announced Saturday.

Airman 1st Class Matthew R. Seidler, 24, was one of three killed Thursday when their vehicle was hit by an improvised explosive device. The three airmen, all in the Air Force, were in the Shir ghazi, Helmand Province, Afghanistan.

Seidler entered active duty in 2009 and was assigned to the 21st Civil Engineer Squadron, where he was an explosive ordinance disposal technician.

“This is a tragic day for Team Pete, the 21st Space Wing, the 21st Civil Engineer Squadron and especially for Matt’s family,” Col. Chris Crawford, 21st SW commander, said in a statement. “We will come together to help Matt’s family and friends through their grief.”

Tech Sgt. Amanda Callahan said that Seidler was unmarried, and that most of his family appeared to live in Maryland, where he was from.

"The pride we'll feel when we see Matt's name on the EOD Memorial Wall at Eglin will not extinguish the sorrow we feel from his loss," Lt. Col. Mark Donnithorne, 21st CES commander, said. "We'll never forget Matt's sacrifice and dedication to his critical, yet dangerous, mission.

At this time, a memorial service has not been announced.
