An Army Reserve CH-47D helicopter assigned to the 159th Aviation Regiment in Fort Eustis, Va., lifts an 11-meter rigid-hull inflatable boat (RHIB) out of the Pearl River in Mississippi Feb. 14, 2008, as special warfare combatant-craft crewmembers use a ladder to board the aircraft during a maritime external air transportation system training exercise. CH-47D Chinook helicopters are capable of lifting and transporting vessels over long distances of land and water. (U.S. Navy photo by Mass Communication Specialist 3rd Class Robyn Gerstenslager)
