South Korean marines stage amphibious landing exercise

South Korean marines in amphibious armoured vehicles waded ashore under the guns of patrolling warships on Wednesday as part of large-scale military exercises that organizers say are necessary to prepare for any North Korean threats.

The amphibious landing practice, held near Pohang on South Korea's east coast, is part of the 12-day Hoguk 22 field exercises, which have included some drills with U.S. troops, such as a river-crossing exercise last week.
