The CWST (Combat Water Survival Test) was broken into three different phases.
1) Swim across the pool with a M-16 (we actually used "rubber ducks" which are fake M-16's that weigh the same but are made out of rubber)
2) Jump into the pool with a LBV (Load Bearing Vest) and M-16 (Again rubber duck), drop the rifle and remove the vest, resurface and swim to the edge of the pool.
3) Walk off diving board blindfolded and swim to the edge of the pool. Video is located below.
Swimming across was fairly easy, as a previous certified lifeguard---I have no problems swimming. Jumping in with the LBV on and taking it off was also a piece a cake. The only challenge is making sure you get deep enough in the water to fully remove the LBV.
The most difficult challenge for me was the walking off the diving board blindfolded. In concept it is a very easy task to accomplish, and I would have been perfectly fine doing it without being blindfolded. However, being lead to an edge of a board by verbal commands, and being told to walk off without having any visual aid whatsoever....was VERY terrifying for me. This challenge was able to strike a phobia that I never realized I had.
I passed all three challenges with flying colors on the first try. Everything being considered, it was nice to do something different for PT rather than the same run and exercises.
