How to Do a SEAL Combat Side Stroke

The SEAL combat side stroke (CSS) is a swimming technique that propels your body forward as efficiently as possible. Meant for swimming long distances quickly while expending as little energy as possible, it is incredibly efficient; since Navy SEALs deal primarily in water-based missions, the CSS is key for all SEAL recruits to learn.



The combat sidestroke is not really a sidestroke. Rather, it is a combination of of the sidestroke, breaststroke and standard freestyle stroke, which means it is more difficult to learn than any of these three individually.
