When the 150 men of class 234 begin Basic Underwater Demolition SEAL-BUDS- training, they have the toughest six months of their life ahead of them. They have been selected from over 1500 applicants. By the time Class 234 graduates, only thirty-two will remain to become US Navy SEALs. This series takes the viewers behind a structured world of sacrifice designed to force BUDS students to the limits of their physical and emotional endurance. It is the most complex, demanding, and gruelling test of commitment ever devised by any commando force in existence.
