Most regular every day folks don't realize how truly traumatic this war, and past wars, have been on our military personnel. Many come home with pent up emotions, anger, stress, hidden fear, panic attacks, nightmares, chronic and acute depression, suicidal ideations... even worse... violent outbursts and blackouts. This is all from a very real response called POST TRAUMATIC STRESS DISORDER. In some it is very subtle. In others it can be very obvious. Either way, it can be crippling to their daily lives, and damning to marriages and families.
PTSD had not even really been recognized, much less be diagnosed as a very real issue relating to mental health, until after Vietnam. Before then, many families whispered quietly about their older veterans who would panic or freak out when a car backfired or fireworks went off at a holiday celebration. They once called this response "shell shock", and sometimes these older veterans would have very real flashbacks that instantly put them back into a combat scenario, and they would go off on tangents about enemies close by, or run and dive for cover.
I am also extending this same benefit to public safety personnel to reduce job stress or manage diagnosed PTSD... AND to the everyday person who has been diagnosed with PTSD.
