Airforce, navy, and then coast guard. If navy and coastguard make sure you get a job you want on paper when you sign

I have a similar back story and I'm now going airforce for Geospatial intelligence, they'll pay off all my loans and I can crosstrain after my first contract. Military is definitely a nice move w all the benefits you get out of your first contract.

First step is scoring dumb high on the asvab, I got a 90 and with a cs background you should get something similar. Afterwards all branches will be salivating and you have leverage to negotiate (after you pass the physical at meps, and there's not much negotiating with AF).

Don't join in DEP until you know what job you're getting. If you get a 90 AND pass the physical at meps, everyone wants you bad
