The United States Navy Sea, Air, and Land (SEAL) Teams, commonly known as Navy SEALs, are the U.S. Navy's primary special operations force and a component of the Naval Special Warfare Command. Among the SEALs' main functions are conducting small-unit special operation missions in maritime, jungle, urban, arctic, mountainous, and desert environments. SEALs are typically ordered to capture or to kill high level targets, or to gather intelligence behind enemy lines. SEAL team personnel are hand selected, highly trained, and possess a high degree of proficiency in direct action (DA), and special reconnaissance (SR), among other tasks like sabotage, demolition, intelligence gathering, and hydro-graphic reconnaissance, training, and advising friendly militaries or other forces. Depending on the availability of platforms, threat level, and environment, different methods can be used for the insertion and extraction of SEALs into a target location. This could include nuclear-powered cruise missile submarines equipped with dry deck shelters, SDV submarines, surface vessels, surface swimming, or other vehicles All active SEALs are members of the U.S. Navy. The CIA's highly secretive and elite Special Operations Group (SOG) recruits operators from SEAL Teams, with joint operations going back to the MACV-SOG during the Vietnam War. This cooperation still exists today, as evidenced by military operations in Iraq and Afghanistan. History Origins Although not formally founded until 1962, the modern-day U.S. Navy SEALs trace their roots to World War II. The United States Military recognized the need for the covert reconnaissance of landing beaches and coastal defenses. As a result, the joint Army, Marine Corps, and Navy Amphibious Scout and Raider School was established in 1942 at Fort Pierce, Florida. The Scouts and Raiders were formed in September of that year, just nine months after the attack on Pearl Harbor, from the Observer Group, a joint U.S. Army-Marine-Navy unit. Scouts and Raiders Recognizing the need for a beach reconnaissance force, a select group of Army and Navy personnel assembled at Amphibious Training Base (ATB) Little Creek, Virginia on 15 August 1942 to begin Amphibious Scouts and Raiders (Joint) training. The Scouts and Raiders' mission was to identify and reconnoiter the objective beach, maintain a position on the designated beach prior to a landing, and guide the assault waves to the landing beach. The unit was led by U.S. Army 1st Lieutenant Lloyd Peddicord as commanding officer, and Navy Ensign John Bell as executive officer. Navy chief petty officers and sailors
