Loyal to the end
Kerry enlisted in the U.S. Naval Reserve in February, 1966, and began active service that August as Ensign aboard the USS Gridley, a Guided Missile Frigate deployed in the Gulf of Tonkin. During his tour of duty, Kerry requested his second tour be in Vietnam, listing his preferred position as commanding a Fast Patrol Craft (PCF) or "Swift Boat." His request was granted, and on November 17, 1968 he reported to Cam Ranh Bay for a month of training.
The Swift Boats had been considered to be a safe place to be during the war, but during that time their role was changed to become more dangerous and combat oriented.
