But I digress. Navy SEALs, like Delta Force, are super soldiers specially trained for unconventional warfare, reconnaissance, and counter-terrorism operations on SEa, Air and Land (hence their acronym moniker). Created by President Kennedy in 1962, the Navy SEALs emerged from the elite of the U.S. Navy to parallel the Army's Green Berets, when tasked to infiltrate and disable enemy jungle camps during the Vietnam War. Since then, the Navy SEALs have evolved into a formidable and revered unit on their own, and is now a part of U.S. Special Operations Forces.
According to The New York Times, Navy SEALs must train for at least six months before deployment, including dealing with free fall and underwater scenarios, demolition training, and engaging in hostage and terrorist simulations. They must also go through a grueling test of endurance; during "Hell week" trainees must run, swim in cold water, and crawl through mud almost non-stop for almost six days, with only a total of four hours sleep. Only about half of the candidates survive training, thus filtering out the incapable.
