No soldier's patch is worn with greater pride than that displayed on the shoulder of a man who has belonged to a combat division. In World War II, as in every past war, the major share of our fighting has been done by our ground troops, particularly those of the Infantry. Most of our Infantrymen belong to divisions which are our Army's principal combat teams, composed of soldiers who are trained and expected to do one primary job fight. This book is not a complete history of our combat divisions. It is, rather, an attempt to assemble for the first time enough material on every one of our divisions to give the average citizen a brief idea of where each has been and what each has done.
