Book excerpt: This is the definitive study of British light tanks of the Second World War. The author draws upon a vast and comprehensive body of archival information and research to explore their technical characteristics and combat performance. The title focuses largely on the very widely used Mark VI, but also covers all the variants that preceded it. The type was truly ubiquitous, equipping the British Army in France, the Western Desert regions, Norway, Sumatra, Persia and India. This book chronicles various experiments and improvisations carried out on the design of these tanks. It ends with coverage of the final model, the Mark VIC, and details of the experimental Lloyd airborne light tank of 1942, which has a number of features in common with the better-known Vickers-Armstrongs designs. Augmented by original photographs and technical drawings, this title is essential for anybody interested in the development of British armoured vehicles.
