I am currently at 17 years in the National Guard, with 8 years of active duty included in the time. Currently a traditional drilling guardsman. I am also rated at 90% (likely soon be at 100%) by the VA. Largest rating is 70% for PTSD (combat related) and 50% for sleep apnea. 20% for a shoulder injury and 3 ten percent ratings. I am very seriously considering submitting paperwork to initiate a military MEB/PEB. My question is will the 70% PTSD rating get me to a 30% military retirement rating? Should I want until I have my 20 year letter in hand? Any advice is welcome.
