Second phase is the dive phase portion of BUDs

It also builds teamwork, but it starts to

incorporate a much greater learning process for

the guys going through.

The majority of the evolutions that cause the

students the most problems is the water work

If a guy isn't comfortable in the water, then he

is not really cut out to be a frog man.

He's got to keep his head about him when he is in

the water. If something goes wrong with his dive

rig or something like that. So, a lot of the pool

work is very stressful. You've got to be mentally

in the game to make it through those evolutions

The men are subjected to continual calculated

harassment by their instructors. To see if they

follow procedures taught in the classroom.

Students are tumbled around and their mouth pieces

torn from their mouths, simulating the effects of

a strong ocean surge.

Students are taught 2 types of scuba

Open circuit, using compressed air bottles

and closed circuit, using specialized oxygen

recirculation equipment.

San Diego bay turns into a combat training area

for practicing underwater navigation.

The men are learning to use a specialized

breathing apparatus, the Draeger LAR-V.

It's a closed circuit, underwater breathing

apparatus, designed for use in clandestine

military operations in shallow water, where

concealment of telltale exhaust bubbles is essential.

In a modern 50 ft dive tower on the BUDs compound,

the men perform free swimming ascents, without the

use of breathing apparatus.

It's all part of learning the specialized

breathing techniques necessary, to be a special

warfare combat swimmer.
