Phase ONE - Conditioning - Phojo-Frog

Basic Underwater Demolition/SEAL (BUD/S) Training Student conducts a drown proofing evolution, with his hands and feet tied, and swims to the bottom of the combat training tank to pick up a face mask with his teeth. He has to return to the surface with the face mask or he fails the evolution. This teaches the students they can still survive in the water even if injured.
