The British Army during the closing years of World War I employed a new weapon,

the tank, to achieve dramatic breakthroughs across the barbed wire and trenches

that otherwise defined the attritional warfare. Though the British fielded their first

technologically-challenged tanks for infantry support, the Army’s pioneering use of

them en mass on the battlefields at Cambrai and Amiens illuminated the revolutionary

potential for large-scale, independent offensive armor operations. As described

by Harold Winton, the British Army’s innovative prowess was on full display by

war’s end with the new Tank Corps that “from a figment of the imagination, had

become a force of 20 battalions and 12 armored car companies,” and that due to its

dynamic performance at the tactical-level formed the crux of new visions for armor

operations.1 The enthusiasm spilled over into the initial interwar period, as the British

Army spearheaded significant technological, tactical, doctrinal, and organizational

advances. These early achievements were nourished by constructive debate over

mechanized versus armored warfare, and by decisions to create a permanent Tank

Brigade and expand the Royal Tank Corps. This was complemented by forward-

leaning experimentation in command, control, communications, and maneuverability

that by the early 1930s placed Britain at the vanguard of transformation to combined

arms warfare.
