Book excerpt: Overshadowed by the United States Army's armored divisions, the separate tank and tank destroyer battalions had the difficult mission of providing armored support for US infantry divisions in the 1944–45 campaigns. This book details the organizational structures and deployment of these units: the standard tank battalions, tank battalions (light), tank battalions (mine exploder) and tank battalions (special), self-propelled and towed tank destroyer battalions. It also covers the tactics used by these units in their attempts to assist the infantry, as well as providing a listing of all the battalions that took part in the Northwest Europe campaign.
