Hi Jason, I contacted you about a week ago regarding my husband's final PPE Review for Marine Corps' TDRL....I finally got through SECNAVINST 1850.4E There is some help there but very little concerning PTSD. My ultimate information goal is to have a list of things that need to be sent to the Marine Corps for final determination as well as what needs to be in this letter from his doctor. Thank you for all of your help.
