The battle for Europe in 1943-45 was one of the greatest military challenges in the history of the U.S. Army. Fighting against often veteran German forces from the mountains of Italy to the beaches of Normandy and the frozen forests of the Ardennes, hundreds of thousands of US infantrymen had to move quickly beyond their training and acquire real-world combat skills with extraordinary pace, if they were to raise their chances of survival beyond a few days. They fought in an age of total war, in which the enemy deployed heavy armor, artillery, air power, and their own infantry firepower in a battle of true equals. Without the drive and blood of the U.S. Army infantry, the Allies could not have defeated the Wehrmacht in Western Europe.

Extensive documentation was provided for the in-theater US Army infantryman, from booklets rather misguidedly advising on how to behave in foreign countries through to field manuals explaining core combat tactics across squad, platoon, company, and battalion levels. This pocket manual presents critical insights from many of these sources, but also draws on broad spectrum of intelligence reports, after-action reports, and other rare publications. Together they give an inside view on what it was light to live and fight in the U.S. Army infantry during arguably the most consequential conflict in human history.
