If you listen to the (mostly left wing) politicians and the anti-war people you would think a couple of years enlistment in the Military turns people into zombie like maniacs suffering from PTSD in varying degrees. The side effects of some modern common prescription drugs available to counter the effects of arthritis and quitting smoking apparently can cause mood swings serious enough to consider suicide (or murder?) that mimic the alleged effects of PTSD. Any former member of the US Military will tell you that they have to undergo a battery of shots in the U.S. and before going overseas. What if some injection or common drug administered in the Military causes mood swings that mimic the effects of PTSD? Don't count on the CDC to investigate.
