The PEB uses the VA Schedule for Rating Disabilities (VASRD) as guidance in their rating determinations, a link to which is here:
VBA 38 CFR Book C (U.S. Department of Veterans Affairs)
Servicemembers are rated on the degree of their disability, as you will no doubt gather from taking a look at the VASRD. I would not say the PEB findings are subjective in an overall sense but they are forced to consider some individual factors in each case (rank, time in service, military specialty).
If he is rated under 30% he is
separated with severance pay, which for him would be base pay x 2 x 3, this equates to 6 months' pay. He will still maintain his Post 9/11 Servicemember's Relief Act benefits. He will not be eligible for medical benefits but his injuries will be cared for by the VA.
If rated over 30% he is
retired with medical benefits, a monthly pension (based on his disability percentage), and all the priveleges that go with having a military ID. Since he has been in boot camp he has not had the chance to enjoy the PX, commissary, and so on and so forth.
Never heard of that condition, I would take a look in the VASRD and also do some research to see if the condition is synonomous with any others (in case that particular terminology does not show in the VASRD).
Good luck and keep us updated!
