I agree Doug, past wars where different. Other services had more involvement compared to nowadays with modern warfare. If a ship got attacked, I could understand a percentage of those sailors would get PTSD. No issue. If a pilot got shot down or had constant fire fights with fighters, could understand that also. With technology now, ships and planes see very little direct action against them. Missiles launch from hundreds of kilometres, thousands even depending on the missile. A plane can shoot down another plane or target from hundreds of kilometres away, never even see the target or only a small image.

I guess this comes down to the individual again. If you had someone who thought further than their job of pushing that button, really processed and analysed the impact of their actions, I would say they could legitimately get PTSD from giving themselves the traumatic thoughts of their own actions. I would still agree though that the numbers would be extremely low. The only reason the Army has higher rates is because of their duty.... land force. Planes and ships bomb land forces. Land forces fight against land forces, all of which land forces are humans. We don't have protective shields, radars or the like. No early warning system for land troops... just the bomb or crack thump of the bullet passing you by.
