I wouldn't take for granted that you can get back in. I knew a number of folks who got out in the 90's (the military was degraded, and airlines were booming) only to get furloughed or lose their pension after 9/11. Fortunately for them the military business picked when the airlines tanked so getting back in was no problem. In the end I was glad I stayed in...I'll retire several paygrades above some of my buds who gapped service.

But in a plausible future economic scenario there may not (likely not) be a major conflict involving large ground forces, force structure increases, and reserve recalls. Getting back in might be problematic depending on force structure, and your age/rank. Easier for enlisted, but still.

Something to consider. If it were me I'd try to get into a career field or job that would be fun or at least tolerable and stick it out.
