In 1950, when he commissioned the first edition of The Armed Forces Officer, Secretary of Defense George C. Marshall told its author, S.L.A. Marshall, that "American military officers, of whatever service, should share common ground ethically and morally." In this new edition, the authors methodically explore that common ground, reflecting on the basics of the Profession of Arms, and the officer's special place and distinctive obligations within that profession and especially to the Constitution.

Comparing military pay with civilian pay, the authors find that military pay in 2017 was above the 70th percentile of civilian pay. It was at the 85th percentile for enlisted personnel and the 77th percentile for officers.
