Chulmae Range, South Korea, Nov. 27, 2001: Army Pfc. Joshua Turknett, Alfa Battery, 5th Battalion, 5th Air Defense Artillery, stationed at Camp Casey, looks over his live stinger missile prior to going to the Chulmae Range, Korea, during Operation Sea Strike. Soldiers from 5th Battalion, 5th Air Defense Artillery fired Stingers at the beachside training range on the West Sea. The exercise was aimed to give the unit more confidence to fire the missiles. The Stinger, which debuted in 1982, remains a core of the Army’s low-altitude air defense.
