The name of this weapon is something of a misnomer, since, as the authors stress, it was never designed to stop tanks - as members of the BEF found to their cost when they tried to do so during the 1940 Battle of France. It was, rather, produced as a weapon to combat light armoured vehicles - and was intended for the Home Guard to deal with such air- and sea-borne vehicles in the early stages of an invasion. This wartime booklet, published in 1944, and illustrated with a dozen photographs, is a guide to all aspects of the weapon including its mechanism, magazine, firing, loading and unloading, sight-setting, aiming, firing positions, maintenance and cleaning.
