This Department of the Army Training Circular, Training Circular TC 7-22.7 (FM 7-22.7) Noncommissioned Officer Guide 7 April 2015, is dedicated to the men and women of the U.S. Army NCO Corps, who have made the ultimate sacrifice and to NCOs presently serving in the Active Army, the Army National Guard, and the Army Reserve. Your Soldiers will seek your guidance; trust you to train them, and to develop them to win the nation's wars. As the standard-bearer, instill pride and strive to live the Army Values. You are "The Backbone of the Army." This TC provides the Army's NCOs a guide for leading, supervising, and caring for Soldiers. While this guide is not all-inclusive, nor is it intended as a stand-alone document, it provides NCOs a quick and ready reference to refresh and develop leadership traits. This TC provides critical information for the success of today's NCO and is intended for use by all the NCOs in the Active Army Component, the Army National Guard, and the Army Reserve Component. The proponent for this TC is the United States Army Sergeants Major Academy. This Training Circular is a guide to develop an innovative, competent professional NCO. NCOs must learn to analyze and evaluate the operational environment to create and apply an understanding of the changing world that confronts them.
