U.S. Army soldiers aim their machine guns during South Korea and U.S. joint military exercise against possible North Korea's attack in Paju, south of the demilitarized zone (DMZ) between the two Koreas, in South Korea, Wednesday, June 8, 2011. North Korea conducted a routine short-range missile test last week in an apparent effort to improve its missile capabilities, a South Korean official said Wednesday, amid renewed tension on the Korean peninsula.
