Jim Vestal/Stars and Stripes Camp Casey, South Korea, July, 1961: A platoon sergeant gives his 7th Infantry Division troops a few pointers on how to safely disembark from a landing craft at Camp Casey's Schoonover Bowl during preparations for Operation Sharp Edge, to be held later in the summer on Korean beaches. Nearly 7,000 troops from the division were to take part in the 24-hour, no-live-ammunition exercise, which used the U.S. Seventh Fleet and American and South Korean jet fighters for simulated bombardment during the landing.
