craig,
there are no qigong techniqes in military, at least overtly but the ARt of WAr is as subtle as a hammer and in use in various stages.
I did taijiquan and qigong on my own time (Korea/Taiwan).
my stated mission was to meet the enemy, engage and destroy! so much for subtlety.
I can honestly say that the military add reality (boot camp) to those who think softness, 'damaging without touch wannabees', walking on water stuff, dancing in pajamas taichi training is da bomb. Reality will sink in real fast on a 5 mile run.
Good for endurance and stamina!
