The United States Navy's Sea, Air, Land Teams, commonly known as the Navy SEALs, are the U.S. Navy's principal special operations force and a part of the Naval Special Warfare Command and United States Special Operations Command. "SEAL" is always capitalized in reference to members of the Naval Special Warfare community. The acronym is derived from their capacity to operate at sea, in the air, and on land. SEALs are male members of the United States Navy. An exchange program with the Coast Guard, which graduated three Coast Guardsmen as SEALs, was suspended in 2011. The CIA 's highly secretive Special Activities Division (SAD) and more specifically its elite Special Operations Group (SOG) recruits operators from the SEAL Teams. Joint Navy SEALs and CIA operations go back to the famed MACV-SOG during the Vietnam War. This cooperation still exists today and is seen in the wars in Iraq and Afghanistan. SEAL Teams The original SEAL Teams in the Vietnam War were separated between West Coast (Team ONE) and East Coast (Team TWO) SEALs. Likewise current SEAL Teams are organized into two groups: Naval Special Warfare Group One (West Coast) and Naval Special Warfare Group Two (East Coast), both of which come under the command of Naval Special Warfare Command at NAB Coronado, California. As of 2006, there are eight confirmed Navy SEAL Teams. The current SEAL Team deployments include Teams 1, 2, 3, 4, 5, 7, 8, and 10. The most recent teams are SEAL Team 7 and SEAL Team 10, which were formed in March and April 2002, respectively. The Teams deploy as Naval Special Warfare Squadrons or Special Operations Task Forces and can deploy anywhere in the world. Squadrons will normally be deployed and fall under a Joint Task Force (JTF) or a Combined Joint Special Operations Task Force (CJSOTF) as a Special Operations Task Force (SOTF).
