Book excerpt: All the guns examined in this new paperback edition of Machine Guns of World War 1 belong to the class known as "automatic" and seven classic World War 1 weapons are illustrated in some 250 color photographs. Detailed sequences shows them in close-up: during step-by-step field stripping, and during handling, loading and live firing trials with ball ammunition, by gunners wearing period uniforms to put these historic guns in their visual context. These fascinating photographs are accompanied by concise, illustrated accounts of each weapon's historical and technical background. The reader will learn exactly what it looked like, sounded like and felt like to crew the German, British and French machine guns which dominated the battlefields of the Western Front in 1914-18, and which changed infantry tactics forever.
