SEATTLE - Members of the Coast Guard's Port Security Unit 313, based in Tacoma, Wash., arrive at McCord Air Force Base, Wash., from a six month deployment to Guantanamo Bay, Cuba. As part of the multi-agency Joint Task Force, the unit provided anti-terrorism force protection by patrolling the waters near the U.S. naval base since Dec., 2007. Coast Guard port security units are deployable anywhere in the world and maintain port security both during wartime and peacetime. The units can respond to any occupied foreign port and can also maintain security for homeland ports when necessary. (Official Coast Guard photo by Petty Officer 3rd Class David R. Marin)
