The present book borrows heavily from earlier editions, but with significant exceptions. It contains a completely new survey of the Vietnam War that brings the story down to the advent of the All-Volunteer Army and incorporates much of the significant recent scholarship on that still-debated chapter in our nation's military past. It also includes a new bibliography and a list of suggested readings for the young student officer. In effect, this revised edition of the textbook represents a blending of the work of some of the Army's best historians over three decades.
