English: Navy Special Warfare Trident insignia worn by qualified U.S. Navy SEALs. Navy SEALs are named after the environment in which they operate, the Sea, Air, and Land, and are the foundation of Naval Special Warfare combat forces. They are organized, trained and equipped to conduct a variety of Special Operations missions in all operational environments. Today’s SEALs trace their history from the elite frogmen of World War II. Training is extremely demanding, both mentally and physically, and produces some of the world’s best maritime warriors.
