The top enlisted man of Fort Carson's Third Armored Cavalry Regiment was wounded in the attack that killed one of his soldiers last weekend.
Command Sergeant Major John Caldwell was wounded when insurgents attacked his vehicle with small arms fire and an improvised explosive device.
The post newspaper, the Mountaineer, reports Caldwell was first flown to Landstuhl Regional Army Medical Center in Germany, then to Walter Reed Medical Center in Washington, D.C.
Caldwell is listed in stable condition.
Twenty-one-year-old Private Joseph Knott of Yuma, Arizona was killed in the same attack Sunday.
He was the first member of the Third Cavalry to die since the unit deployed to Iraq last month.
