Hi! You've mentioned wanting to join JAG. Why don't you join the army now? It would help the financial issues and you're already interested in the military. I just found this link:

https://www.airforce.com/careers/specialty-careers/jag/entry-programs/active-duty-military#:~:text=FUNDED%20LEGAL%20EDUCATION%20PROGRAM%20(FLEP)&text=If%20you%20are%20selected%20to,while%20you%20attend%20law%20school.

I selected the other slots and there is also a student entry program. You can join as a student in law school. The Graduate Law Program (GLP) is also available it looks like you can join this program at any point of your law career. Maybe it would be best to connect with them now through the JAG entry programs.
