An introduction to the people and events that have made the United States Army one of the strongest military forces in the world. The volume profiles the leaders and the accomplishments of the US Army from the beginning of its history to the 21st century. Entries on top military and civilian leaders, notable enemies, logistics/weaponry, and significant wars are all listed within the text. Clayton Newell emphasizes the actions that the US Army takes to continually transform itself to remain a dominant force in the world. There is a listing of the army casualties by war, as well as lists detailing the total number of those who served in the army, the number of army battle deaths, as well as war injuries. Several appendices accompany the dictionary, covering topics such as the resolution of the Continental Congress adopting the Continental Army, the appointment of George Washington as Commander-in-Chief, campaigns that the US Army has been involved in, along with others. A bibliography refers to sources for additional information.

Contrary to many assessments that immediately followed the end of the 1991 Persian Gulf War, that war was neither short nor decisive. The 1991 conflict was the dramatic manifestation of long-standing antagonisms among the principal participants, and its results continue to have a profound effect on the region, a fact that can be seen most clearly in the current U.S.-occupation of Iraq. It is therefore important to determine, on the diplomatic side, just how the war got started, how it was fought, and whether the dramatic ground campaign should have exceeded the mere hundred hours it lasted in order to bring about a more decisive conclusion. With the seemingly endless follow-up to the war continuing, The A to Z of the Persian Gulf War 1990-1991 draws together the results of assessments of the war by a multitude of commentators. This is accomplished through an introduction, a chronology, a list of acronyms and abbreviations, a bibliography, appendixes, and hundreds of cross-referenced dictionary entries on many of the significant civilian and military persons, crucial diplomatic and political actions, as well as the essential military aspects, including the strategy and tactics, the encounters and battles, and the forces and weapons deployed by both sides. As the situation in the Middle East continues to deteriorate, this reference provides an important historical perspective on an increasingly critical issue.

On the eve of the Civil War, the Regular Army of the United States was small, dispersed, untrained for large-scale operations, and woefully unprepared to suppress the rebellion of the secessionist states. Although the Regular Army expanded significantly during the war, reaching nearly sixty-seven thousand men, it was necessary to form an enormous army of state volunteers that overshadowed the Regulars and bore most of the combat burden. Nevertheless, the Regular Army played several critically important roles, notably providing leaders and exemplars for the Volunteers and managing the administration and logistics of the entire Union Army. In this first comprehensive study of the Regular Army in the Civil War, Clayton R. Newell and Charles R. Shrader focus primarily on the organizational history of the Regular Army and how it changed as an institution during the war, to emerge afterward as a reorganized and permanently expanded force. The eminent, award-winning military historian Edward M. Coffman provides a foreword.
