Sgt. Kerry Williams, squad leader, monitors the progress of his squad as they assault up to an enemy position during a live-fire range. Marines from Battalion Landing Team 1st Battalion, 6th Marine Regiment, 24th Marine Expeditionary Unit, spent three days in the field perfecting small unit leadership through various exercises. Marines practiced leading squads and fire teams on patrols, taking enemy fire, closing with their foe and using their fire power to win the battle at Fort Pickett, Va., Sept. 16-18. Infantry units focus on a decentralized leadership style that allows them to be more agile on the battlefield. Photo by: Cpl. Randall A. Clinton
