Which branch of the military should I join to help in civilian life, for the best quality of life, and has the most resources available?

The service is not here to make your civilian life better/easier. It is here let you serve something bigger than yourself, the Constitution and the Nation. We do not have time to let you get your act together nor grow up, etc. 6 moths after you join, you could be fighting for somebodies life in a foreign country. As Kennedy said " Ask not what your country can do for you, but what You can do for your country."

I’ve been in the navy and currently serving in the army. Honestly, it depends on your GT score from the ASVAB. The higher your GT score the more rates (navy) and MOS (army) will be available to you. Coast guard is similar to the navy.

Every branch is different regarding basic training. If you elect to go to the army, they’ll send you out based on availability if it’s one station unit training (OSUT) or for advanced individual training (AIT). Especially with COVID happening, I don’t know how they’re shipping trainees out. On the other hand, navy is a bit different. Once you’ve selected your rate you can decide when you’d like to ship out to Chicago.

Everyone has their own preference to their MOS and rates. I’d definitely looking into them once they gave you your choices and see what you like.

Resources are always available to all service members regardless of location. Depends what type of resource you’re trying to explore.

Quality of life varies per unit and varies between each branch. Life in the field is A LOT different than life in a ship.

What have your recruiters told you?

Don't think about a job or branch that will make you a more marketable civilian. That's a common mistake. You don't join to be a good civilian. You're already a marketable civilian with your degree, free education is one of the best things you can walk out the military with. Join the branch you want because of the culture and the MOS you want because you'd enjoy doing that job for 20 years. If you like the job, you're going to stay on doing it and retire. If you like the organization you're going to stick with it. If you don't like the job you're not going to finish your contract and stay in that field. Don't worry about what transfers because if you like it you won't be a civilian for a long time.

What about after retirement, you may be wondering? If you stay in your field one of two things will happen. Either, you will need some more education and certifications to be competitive with your civilian counterparts (like IT, Cyber, HR, or medical) or you'll transfer into something very niche working for the government. You'll see the second one a lot with retirees who went to work at Range control, or barracks manager programs, or any of the thousands of MOS Immaterial jobs that need to be filled by someone with leadership and managerial experience. A very large amount of people choose not to work in their old field at all. Once you start collecting your pension, you have enough supplemental income to choose a field you enjoy rather than one that pays well enough. You can be retired in your early 40s collecting 40% of your base pay, plus any disability for years of wear and tear, and return to college for a degree in a field of your choosing. There's a lot of financial freedom in retiring at 40 with all your bills paid, house paid off, thousands of dollars of passive income a month, and a whole GI Bill waiting to be used.

So, don't think about what will set you up for success as a civilian, because you're either going to love it and stay, or hate it and leave. Think about how you'd like to spend the first term of service and what you'd like to be doing
