United States Navy SEALsThe United States Navys Sea, Air and Land Teams, commonly known as the Navy SEALs, are the U.S. Navys principal special operations force and a part of the Naval Special Warfare Command and United States Special Operations Command.[3] One of the SEALs primary functions is to conduct small-unit maritime military operations which originate from, and return to a river, ocean, swamp, delta, or coastline. SEALs can negotiate shallow water areas such as the Persian Gulf coastline, where large ships and submarines are limited due to depth.[4] The Navy SEALs are trained to operate in all environments (Sea, Air, and Land) for which they are named. SEALs are also prepared to operate in a variety of climates, such as desert, arctic, and jungle.All SEALs are male members of the United States Navy.[4][5][6][7] The CIAs highly secretive Special Activities Division (SAD) and more specifically its elite Special Operations Group (SOG) recruits operators from the SEAL Teams.[8] Joint Navy SEALs and CIA operations go back to the MACV-SOG during the Vietnam War.[9] This cooperation still exists today and is seen in the wars in Iraq and Afghanistan. - Wikipedia
