A Fort Wainwright-based soldier has been killed in Afghanistan.

The Department of Defense says 21-year-old Brandon Mullins of Owensboro, Ky., was killed in Kandahar Province on Aug. 25 by a roadside bomb while on patrol.

Mullins joined the U.S. Army in February 2010 and completed training at Fort Benning, Ga.

He was a member of the 1st Stryker Brigade Combat Team, 25th Infantry Division based at Fort Wainwright.

His brigade deployed to Afghanistan in April.

Three other members of his brigade were injured in the explosion.
