This is the classic WW2 sniping handbook. The author had a much experience in sniping on the western front in the First World War, and he wrote his experiences down for the use of troops and the Home Guard at the beginning of the Second World War. This important manual covers all aspects of sniping and is a first class introduction to the subject both then and now. At the start of the Second World War, Armstrong became an instructor in the Sniping Wing of the Small Arms Schools at Hythe and Bisley. In 1942 he became Commandant at the Royal Marine Sniping School.
