BUD/S is the first of many obstacles one must overcome to become a SEAL. This course has been designed to test a man in many things, but ultimately it determines a man’s will to succeed under any and every condition.
When you first enter BUD/S, there is a roughly three-week orientation phase. During this time, candidates will be exposed to all of the elements of BUD/S training, giving them the opportunity to acclimate and prepare for what’s to come.
This orientation phase is much like being in phase one of training. The only major difference is the tempo and intensity.
