I think you’ll still qualify for Tricare after you get out. Before my Dad passed, he was on Tricare (after having been out of the military for decades) and I think they only just recently started charging for it the past few years, but it was still ridiculously cheaper than any private health insurance rates (for him it was something like $12/month vs $600/month private insurance). I stayed away from getting him on because I assumed there was something wrong with it, but nope, I only regret not getting him on Tricare sooner.
