Is there anything, anywhere non-military that teaches you discipline and self-esteem through(read on).?

military type training/environment? Ive always been attracted to the military type lifestyle that teaches discipline,honor, and courage. But I do not want to be in the military for reasons that I do not believe in. Is there any non-military institution that teaches you all of the above and you wear uniforms and are apart of something greater than yourself but not a criminal type institution (army/marines etc with people that dont care about you and you are just a statistic to them, helping them with their own goals of world power...)
