Hubby's commander's letter was done in January. Hubby was MEB/PEB'd for PTSD. The commander's letter then was accompanied by about ten questions that the commander had to answer about his performance. Her letter stated that she had not seen any problem in his work performance until after his return from hospitalization, but had after hospitalization. She stated that while she saw little impact on his physical ability to perform his job, she did notice that he could no longer function because of his mental problems since his return. (She had gone with me to the hospital to talk with his doctors, and she got to know her soldiers very well personally.) My understanding is that now commanders have a 36 questions yes or no form about your performance. My understanding of the intent behind the form is to give a better understanding of your performance, including the mental part. Alot depends on the NARSUM that you have. The more descriptive your doctor is on how it effects your job, the better off you are. Our NARSUM awas 12 pages. Check your NARSUM and make sure it describes ALL your limitations-- physical, mental, social, sexual, etc. In the end, Hubby was rated 70% PDRL, but I credit a very descriptive and thorough NARSUM for that. Hope this helps ease some of the anxiety associated with the process.
