OAK ISLAND, N.C. - A crewmember of Station Oak Island removes an M-240 machine gun from the bow of a 47-foot Motor Life Boat after an evening patrol on the Cape Fear River, April 29, 2011. One of Station Oak Island's primary missions is port and waterway security, as Cape Fear is the gateway to many shipping lanes and contains the U.S. Army's ocean terminal at Sunny Point.
