Sea, Air, and Land

Described as one of the world's elite maritime commandos, the U.S. Navy SEALs are adept in conducting combat missions in different environments: sea, air, and land. Their ability to operate effectively in small numbers, in and out of the water in a clandestine fashion sets Navy SEALs apart from other special operation forces.
Within the Naval Special Warfare Command is a SEAL team that is task to conduct special counter-terrorist missions. This covert unit, called SEAL Team Six or DevGroup, is comparable to the Army's Delta Force.
