Targetting the care is the key rather than introducing some MOD wide policy which is directed at all ex-service personnel. If there is a relationship between PTSD or CSS and criminality post service, then some Services or indeed Arms may well be subjected to focussed assistance. I know PTSD may affect all but I would wager that the combat arms in the Army and some trades within the RAF may be more susceptible/higher probablity. Just a thought.
