When it comes to long-term water survival scenarios, you can only tread water for so long. That’s why we teach a skill called drown proofing and prone float. In a turbid, open-water environment, you may have random wave action crashing over your face. So you protect your face by lying face down in the water and then will to breathe
at an interval that’s comfortable for you. As you can see, Petty Officer Pasquale is face down in the water using his hands
to scull and supplementing with a modified frog kick. The key is staying calm and demonstrating proper breath control and you can sustain a longer period of time.
