Book excerpt: Regardless of technological and doctrinal advances, final mastery of any battlefield ultimately depends upon the tight-knit group of soldiers trained to direct fire, move, take ground and hold it. This book examines the infantry combat methods of World War II. It draws on the training manuals of the time and first-hand accounts of frontline action and covers the organization and tactics of squad, platoon, company and battalion. It identifies the differences between German, American, British and Japanese approaches and demonstrates how these evolved in the face of changes in the battlefield environment. Motorized infantry tactics are also covered together with each army's responses to the continuously growing challenge and shifting patterns of anti-tank combat and combined operations with armor.
