You don’t declare you have PTSD it is diagnosed by a psychiatrist. You are then referred for treatment with a psychotherapist usually CBT, but if you’re lucky you could receive EMDR, often followed by courses of anti depressants. Anyone going into protection command would be subjected to stringent psychological profiling especially an ex serviceman who has recently been posted to Afghanistan and was wounded as a result.
