CAMP SHELBY, MS - The Army's Warrior Leader Course is a big step in a soldiers' progression to Staff Sergeant. Sergeants take part in field leadership exercises, physical training, and operations. But for Sergeant Nathan Brown, his behavior at the course means he'll have to try again.

Brown, an Infantryman (11B) from 155BCT, was attending the Warrior Leader Course to further his career and make himself eligible for promotion. His record was impeccable until a recent exercise at the Urban Operations (MOUT) town. He was armed with twenty blank rounds -- already expended moments after the exercise began. When tasked with clearing a room, he went with the only option he had left - his knife hands.

Administrative specialist SPC Katherine Young was present the day that SGT Brown lost control.
