A Fort Riley soldier from Idaho has been killed in Afghanistan.

The Defense Department says 24-year-old Pfc. Cody Moosman died Tuesday of injuries he suffered when his unit was attacked with small-arms fire in Paktika province, near the border with Pakistan. Republican Sen. Jerry Moran, of Kansas, says Moosman was on guard duty at the time.

He was assigned to B Company, 1st Battalion, 28th Infantry Regiment, 4th Infantry Brigade Combat Team, 1st Infantry Division.

Moosman was from the southeastern Idaho town of Preston. His family issued a statement Wednesday saying he told them starting in the third grade that he had wanted to be in the Army. He enlisted in 2010.
