I tried different calculators but i cant grasp the concept. I was medically permanent retired at 70 percent PTSD. Va i have 90 percent, 70 ptsd, however, I get this at 100% iu permanent with no exams in the future. Anyone can tell me how much would I get if anything with crsc, or is it just not worth the time applying, all is combat related including dod rating. I should get 1,800 per month from dod, but i called them and they haven't received my VA rating yet, so thats gonna chance im pretty sure. Any help, thank you.
