Everytime I hear 'Department of War', it just saddens me. Warfighter is the same.

"When the way prevails in the empire, fleet-footed horses are relegated to ploughing the fields; when the way does not prevail in the empire, war-horses breed on the border." Tao Te Ching chapter 46.

I work in the defense industry. I have not heard a single person say Department of War or DoW.
