Although only 100 examples were produced, the 155mm Gun Motor Carriage M12 served with distinction as an infantry-support weapon and in particular as a bunker-buster during the U.S. assault on the Siegfried Line in the winter of 1944-45.

Spread through 144 pages, almost 200 photos, nearly even divided between photos of the sole surviving example and vintage development and combat photos, including numerous previously unpublished images, chronicle the history of this pioneering self propelled gun and its companion M30  ammunition carrier.
