So I was medically discharged from the Marines in November 2004 for Bilateral ankle reconstruction and was rated at 10% and given severance pay, want to say around 6-7K. I filed with the VA after being med boarded and was awarded 60% for service connected disabilities 20% per ankle(40%) for both and also 10% tinnitus and 10% surgery scar from ankle recon. I am basically trying to figure out what the advantage of getting medically retired is, and if there are any disadvantages.... I repaid my severance the first year after being discharged to the VA. I served 3.7 years in the marines and was an E-3 when I got out because I was on medical hold and could not be promoted. So what do I gain in potentially being awarded medical retirement? Also, How would it affect my current 60% VA disability rating(which is currently being reviewed for an increase)? Is there any back pay due to me from the military if I do in fact get awarded a medical retirement? Sorry for all the questions, but this is the first I have heard of this option and it definitely has peaked my interest. Thanks for the help
