As a senior NCO let me say authoritatively that the Purple heart is NOT being given for PTSD.
From one SNCO to antother: Read the Air Force or Army Times. They are actually, seriously, considering it. Not happening yet, but in today’s AF/AR, it really would not surprise me.
A lot of this “PTSD” is likely after effects of all the drugs they give us over here. Hell, in ‘06 a buddy of mine, after returning from AFG would not go to sleep before his wife. If he did, when she came to bed, it would startle him awake, and before he realized it was her he was attacking her. After six months this went away. The docs blame it on the malaria pills they make us take. I personally have some really effed up dreams from them.
