what it takes training
And they all went through some of the most demanding and arduous training of any military force in the world. All SEALs must go through the 24 week Basic Underwater Demolition/SEAL school and then a 28 week SEAL qualification training program. Only 1% of sailors who enter BUD/S school complete it -- and that's not the end of training. Training for a first deployment can take as much as 30 months.
