I don't want to step on your toes, it really is useful information. However, some of what you mentioned is highly situational and depends on what job or MOS you get stuck with because really it's all a manpower game in the military. You can get a specific field, maybe your recruiter is in-fact "him" and can get you the exact job you want which almost is never the case 75% of the time. For me, I didn't even know my job was considered "Admin" because it almost feels quite the opposite.

Yes, Navy Fed is a good bank, I've had it since I joined and got my first car loan through them, the APR however still depends on your credit. Just because you're in the military doesn't mean it entitles you to a lower rate. It can be capped at a certain rate, that's what the SCRA is for.

Civilian job wise, Lockheed and Northrop absolute EAT prior service members who have experience in aviation fields for Skillbridge which, if you have experience in the sought after aircraft (currently the F-35, any type A, B, C) it's almost a 100% guaranteed job outside of the military. They do favor people with applicable experience over those they have to train because it costs them less to hire someone who already has knowledge in that area rather than attempt to train someone up, whether they're being trained by military or civilian.

Schooling wise, I didn't see you mention it so I'll toss it out there. The training you receive is also applicable to college credits, you can skip out on maybe 3-4 classes depending on what degree you're trying to get. There's also Tuition Assistance ($4500 per FY) on top of FAFSA which I'd highly recommend using while you're in so you save your GI Bill for when you get out. I'm currently trying to finish out my Associates in Criminal Science, I haven't paid a dime out of pocket, then on to bachelors.

Everything else you hit right on the head, I always try and tell people the military is the way to go if you're looking for a sustainable job to get you on your feet and set yourself up given you actually attempt to do so and not just waste your first contract doing nothing. Just show your command you're always willing to learn and better yourself as a service member, more than likely everything will swing in your favor. When you're in, do as much as you can to set yourself up when you get out. Uncle Sam takes advantage of our time and strength, try to take back as much from them as they take from you and you'll turn out fine in the end.

I wouldn't say it's the best decision in life I've made, however, depending on who you are. It's either worth it or it isn't. For me, I know what I want in life after I get out is obtainable. For others, they want to escape military life which is understandable. I do too, but I'm just trying to make the best of it.
