When the first tanks were deployed by the Allies during World War I, a defensive weapon had to be found to counter this new threat. Since artillery was not really suitable for this task, the warring parties eventually developed a special weapon for it, known as the anti-tank gun. Franz Kosar describes in this book the entire development of anti-tank guns from their beginnings in 1916 through the interwar period, World War II, and into the post-war era. He takes into account the specifics and weapon models of individual countries such as Germany, France, and the USA.
