The assessment is only for those who have been in active combat. I was in the navy, personally. You have to ask for an assessment to be done, and perhaps even insist on it. In fact, this concerns people suffering from post-traumatic stress disorder, and not the mission support team.
People are not always comfortable at the thought of going to their commanding officer to ask for an assessment. These assessments are part of new procedures, and I tried to make sure they would apply to everyone, but that was turned down. Only those who have served in operational forces may receive the assessment.
