Pizza and King, an option to consider might be non-enlisted employment with one of the armed forces. Long story short, I had a relationship fall apart (partly for being trans, partly other reasons) and ended up unemployed in a bad economy as result. DARPA wound up supporting my education, putting a roof over my head, food on the table, and keeping me off the streets. Not the same as the GI bill and not the same as working for a defense contractor but I'm quite thankful for the support. It was the second time I worked for the Navy, the first being a civilian GS-03 position keeping some of the wheels turning at one of their bases.
