By 1920 the Red Army fielded an overwhelming array of armored cars and armored trains, while tank detachments had begun forming in earnest. These armored units played an important part in consolidating the newly won Bolshevik empire in the early 1920s; as a consequence of the fact that railways were the strategic arteries that essentially controlled Russia, armored trains have never played such a significant role in military history as they did in the Russian Civil War. This title details their management, construction and repair, personnel and training and combat on all fronts, as well as discussing Trotsky's armored train, in which he conducted 36 tours.
