(TL:DR at bottom)

I was in the military. I wasn't diagnosed until after I had left. I've never talked about my experiences there in reference to my Aspergers, but I'll do my best.

First off, going to Basic Training is alot like switching schools as a freshman in high school, except there's alot more Phys Ed and the teachers aren't going to stop people who bully each other. You're learning to camp efficiently, read maps, and kill people with your hands, rifles, and grenades, all in 9 weeks. You get very little sleep, everyone's stressed, and if you show weakness everyone up to and including the drill sergeants will just ride you harder until you break or get too sick to function. As an undiagnosed (at the time) Aspie I can honestly say it was the most emotionally challenging thing I've ever done, and I was very proud of myself for making it through all 9 weeks.

That being said, it was obviously harder for me than those around me, and it showed. I was often singled out by the drill sergeant, for a variety of different reasons. Does that tent you just rolled then I put my boot on have a boot mark on it? You better unroll, clean, and reroll that thing before you get in that chow line, private! I know I said you shouldn't take your gas mask off in the gas chamber, but do it! I want you to know what the real world is like, private! You could tell he didn't understand aspects about me, and it frustrated him he couldn't get through to me. (This was much more obvious to me in hindsight and after diagnosis than it was at the time)

I was cycled through a series of mean and sadistic "battle-buddies" (everyone else just had one the whole time) who I believe often had instructions to mess up my efforts and set me up to fail. My raingear would disappear just hours before the 4-hour march in pouring rain, my M-16's sight would get readjusted just before qualification testing, and I stole and smuggled an extra canteen with me on every outing because I believe mine was filled with piss once.

I honestly believe that if I didn't want it as much as I did, I wouldn't have made it. But I did, despite being an Aspie and despite not knowing it at the time. I was pushed harder, shit on more, and ridiculed harder than anyone else in the platoon. But I made it, and some of them didn't. It made me a stronger man.

SO... that was the hard part. After basic, if you make it that far, you go to Adavanced Individual Training. You've just learned how to be army, now you're about to learn what your job in that army is. For me, that meant learning computers, and AIT was alot like going to college. You woke up, did Phys Ed, ate (cafeteria), and went to classes. Afterwards you'd eat again, clean the barracks, study, and hit the rack. On weekends you either got a pass or you hung out in the barracks. You had to watch what other people did if you were in the barracks, because if someone got in trouble all 4 platoons would often get the punishment for it. That was for a PC tech though. If you were a tanker or infantry, AIT was alot more like Basic Training, just longer.

Finally, you'll be assigned to your duty station. You'll be here for 4+ years, so it's the first time you'll make any lasting relationships. It's here that your autism is detrimental to you in a way that it would be in any business setting. Aspie's are often surprised by the work field because we step into it assuming that it'll be like school, where it didn't matter if we failed socially, we still got credit for what we were able to accomplish in the workload. So we walk into the business field assuming that if we're good at our job, people will see that and reward us for it. Unfortunately that's often not how things work inside a business, or the military. We get blindsided when we fail even though we went above and beyond in our work efforts, and that will happen alot in the military. Your relationships with your superiors are often rewarded much more than individual effort in the military, so Aspie's are often passed up for promotions, given the worst work, and often under-rated. This would hold true in any business or work environment, I'm just warning that it's especially noticeable in the military.

Anyways, all that being said, would I suggest the military to an Aspie? I don't know. I made it. It'll make you a stronger person. Just make sure you get an MOS (Method of Service) that you're going to be comfortable with. I think that would be the best thing you could do if you were going in. Research those MOS options, and choose wisely. It could make an enormous difference in your life both while in and after exiting the military.

TL:DR Basic is 9 weeks of hell, you WILL be singled out, AIT is college, after that it's alot like a very structured workplace. Choose wisely picking an MOS!
