Among the most successful armoured vehicles produced by American industry - known as the Arsenal of Democracy - during the Second World War were the M2 and M3 half-tracks. They served on every battlefront and were as recognizable as other famous American wartime vehicles like the Sherman and the Jeep, and around 40,000 were produced between 1941 and 1945\\. They were easy to assemble, operate and maintain, and their versatility allowed them to fulfil a variety of purposes. This volume in Pen & Sword's LandCraft series traces the design, development and manufacturing history of the M2/M3 and describes its operational role within the Allied armies. A selection of archive photographs showing the M2/M3 in action gives a graphic impression of how adaptable these vehicles were and records the range of equipment they could carry. The book is an excellent source for the modeller, providing details of available kits, together with specially commissioned colour profiles demonstrating how the M2/M3 used by different units and armies appeared.
