As the author shows in his wide-ranging and authoritative study the technique of sniping adapted rapidly to the conditions of static warfare that prevailed through much of this conflict. His account follows the development of sniping from the early battles of 1914 through the trench fighting and attritional offensives of the middle years to the renewed open warfare of 1918. He concentrates on the continuous British and German sniping war on the Western Front but it also looks at how snipers operated in other theatres Gallipoli Salonika and in Russia. Sniper training field craft and counter sniping measures are described in detail. There is a full reference section giving the specification of sniping rifles of the period and assessing their effectiveness in combat.
