The "Warrior Monk" term came from Gen Zinni (USMC) just before he retired. Amazing how free-speaking some of the higher-ups can be when they hand in their retirement papers and no longer have to be politically correct and speak as their "masters" speak.
He spoke to some organization about the decimation of the military fighting man (and woman) by the political correctness of the military of that day. Declared something along the lines that the politicians (civilian and military) couldn't have a guy who is trained to kill, destroy, sacrifice, do the dirty work involved in the protection of the USA and then be restricted to a "monk-like" existance when actually at their home base. No smoking, no cussing, no drinking, no strip clubs, no hell-raising like 18-25 year old warriors can do, etc. Said it was asinine for the higher-ups to think a kid would finish work, and then only go straight to some continuing education, then home to study military education, restrict his outside life to be a civic leader, a church leader, boy scout, etc. Said it was unreasonable and irresponsible to demand that of those who worked so hard in the home training fields (as well as deployed) to live under restrictions that basically castrated the soldier/marine/airman/coastie, etc.
Used to have a copy of the speech, but it's long gone. But, I'd buy the man a tall, cold beer for putting that term in the spotlight. He's absolutely right...good luck all.
