"The U.S. Army exists for one reason-to serve the Nation. From the earliest days of its creation, the Army has embodied and defended the American way of life and its constitutional system of government. It will continue to answer the call to fight and win our Nation's wars, whenever and wherever they may occur. That is the Army's non-negotiable contract with the American people. FM 7-0 is the Army's capstone training doctrine and is applicable to all units, at all levels, and in all components. While the examples in this manual are principally focused at division and below, FM 7-0 provides essential fundamentals for all individual, leader, and unit training."-From the Preface.
