By John Cantlie SURCs have many missions, including inserting and extracting ground forces. Ramadi, the southwest point of the Sunni Triangle, is a well-known insurgent stronghold. After all is said and done, it's about boots on the ground. On patrol with the old reliable .50 caliber machine gun. Twin 440-hp Yanmars move the 12-ton SURCs to about 40 miles per hour. Patrol and intelligence gathering are extremely dangerous. Back at base, safe and sound this time, the crew prepares for some precious time off before they head out on another precarious mission.
