This 1949 US Army Chemical Corps study examines the history and development of man-portable and mechanized flamethrowers (Allied and Axis); their use in the South Pacific, Central Pacific, and the CBI as well as North Africa and Europe; and their employment against the Allies. It is rich in anecdotes and descriptions of company and platoon level combat. A summary section examines issues ranging from tactics, training and employment to maintenance, supply, and fuels. This study includes 21 appendices mainly training memoranda, pamphlets, and training circulars. There are an additional 32 sketches and photographs. This is a high resolution typescript that was never published; it was a first draft circulated for comments. Image and type clarity are very good. Series: Chemical Corps Historical Studies
