It is a difficult path...but one can be spiritual in nearly any setting. Self-transformation, not assent to religious doctrines, is the goal of a spiritual life. My advice: Be selective in the military occupational specialty (MOS) that you choose. I recommend that you veer away from combat arms. I say that as a retired 1SG who invested 22 years in the Infantry. The military was a rewarding but very challenging road I took. I was fortunate...I never went to combat and never fired a weapon in anger. From the end of the Vietnam War, 1974 to the Persian Gulf years, 1996, I trained but was never called on. Since leaving the military, I found the Buddhist Path...I call myself a follower of the Dharma. I like to think of myself as compassionate and caring rather than crudely violent as even today, in my present job as a civilian gate guard at Ft Lewis, I am required to strap on a 9mm pistol, cuffs, baton, pepper spray as I go about my duties. I protect people...you can too. I wish more people in our position practiced the Dharma. Perhaps I should not have responded...this was my first post. I am a beginner's beginner...never attracted to rituals, robes, chants, prostrations, deity visualizations, lineages, schools of Buddhism, etc. You want to choose the military...go for it. Just know/practice the 4 Noble Truths and 8 Fold Path in the process. That alone is all that I can handle or practice in this lifetime. In your journey, take three books: Bhikkhu Bodis's, "The Noble Eightfold Path", "Going For Refuge Taking the Precepts" and Buddhadasa Bhikkhu's "Handbook for Mankind". Include meditation in your daily routines and you will be just fine IMHO.
