I agree with you here. In the armed forces, you are at the epitome of learning about combat, fighting, surviving, and sacrifice. No arguement here. I think that boxing, Thai boxing, etc, will produce a set of beliefs and philosophies in each of its individuals, it is just a different set than those that are laid out previously by the Eastern martial arts/fighting styles. Watch The Contender. Listen to how they talk about "respect for the sport," and "bringing the best they can to the sport," and other such statements. It is there; you just have to look deeper for it.
