navy UDT (underwater demolition tech) and SEALS (sea air land) units spend more down time than actually on missions. i've met SEALS that were solid muscle, and some that were wiry (thin and flexible) and more that were my body type. any operative will have his specialty and they are encouraged to seek outside training. most guys would come in with a rudimentary knowledge of self-defense, but after six years (each tour) they would of course have a more in-depth knowledge. there are guys that spend every waking moment thinking about weight training, others who would spend their time training in martial arts (everything from tae kwon do to ju-jitsu to aikido). it all depends on the person and what they wanted from the experience. you're basically being paid to be in top physical condition, so it's up to you to fuldill that requirement.

while the CIA recruits from many different employment pools, they do have many ex-special forces members. some special forces members find civilian life boring and enlist themselves as mercenaries.

back to the OP: it would be impossible to pick one of the special forces and say they are the best martial artists. too many outside factors affect who excels in martial arts.
