Omaha Beach Scene from Saving Private Ryan.

The great British army officer Sir John Hacket stated:

“The military makes demands which few other callings do. Emotionally disturbed people talk about being trained to kill.

"The whole essence of being a soldier is not to slay but to be slain. You offer yourself up to be slain, rather than setting yourself as a slayer. One can get into very deep water here, but there’s food for thought in it.”

The essence of warfare is the death of the soldier. The "enemy" is a smokescreen. As we become aware of this truth, our attachment to war diminishes--awaken from the nightmare of history.
