Fortunately, you are one of many and kudos to you. Grown ups will accept the unpleasant bits of life an make good of them. Thanks for your service.
A word to escaping deployments when I was in service...I began my first enlistment while Vietnam was still very much in the news. People were getting dead at a much greater rate there than they are in the ME. That's no excuse to be anything less than a man. We weren't exclusively all-volunteer at that time, either. The rich kids were getting deferments for college while those less fortunate were being sent to the meat grinder. Women were rare enough and had "traditional" jobs in the military.
Man I could only imagine what it was like for the guys in Vietnam. For me it just didn't feel right for me to try and talk my way out of this deployment, although I could have very easily done so with my DOS being so soon after our expected return date, if you join the Military being deployed is something you are going to have to deal with sooner or later, if that bothers you don't ******* enlist. When I worked Separations we had a guy who said he was waiting to see if his job would become deployable in the next coming year, and if it did he would separate, this clown was only in the Military for the benefits, nice bonuses and the safety of a non deployable job, that shit pissed me the **** off.
The 'Nam era was different from today's military in many ways. Homosexuals, while there, were very low-key. Recall that society overall rejected homosexuality in those days. Very, very few were "out of the closet", and most of them were entertainers, not soldiers. Nobody would have posed the question, let alone even considered telling.
Then there's the issue of pot. Talk about a kinder, gentler military...at least towards each other. The enemy caught hell, the the smokers were pretty cool with each other.
There's not real correlation between the military that was then and the military that is now. My brother retired from the Marines because he was disgusted with what a bunch of pansy-asses they had become.
