The Special Forces Underwater Operations Combat Diver Course. This is one of the tougher schools the Army has to offer. If you make it through the OL-H, it is not too difficult physically...but you still have to learn dive tables, physiology, tides, waves, and currents, CPR, submarine lock-in/out, etc. Below is a general overview of the course when I went through...(it was harder back then)!
Train personnel as qualified military combat divers trained in waterborne operations to include day and night ocean subsurface navigation swims, deep dives, diving physics, marine hazards, tides and currents, submarine lock-in/lock-out procedures, and closed-circuit and open-circuit swims.
Morning formation, PT, boat house boogie (FAST 2 mile run), conditioning in pool, which consists of laps and flutter kicks, instruction in dive equipment and procedures.
"Ditching + Donning": enter pool, swim underwater to deep end at depth of 15 feet, remove face mask, snorkel, fins. Twin tanks left on bottom, placing weight belts on top. Take one breath of compressed air, surface, breathe, go down, put weight belt on and other equipment, begin using compressed air. "Harassment Dive" :Get in water, swim around edge at the bottom, and get "harassed" by instructors, face masks pulled, fins removed, oxygen tanks removed, etc, for an hour. Failing either of these exercises results in discharge from SCUBA school. Classes. 500m navigation dive evaluation.
Dive, Dive, Dive...day and night, 1500m navigation dive evaluation, classes, etc. etc. etc.
More night dives, team swim, 3000m navigation dive evaluation, end of course test, FTX, GRADUATION!
