The M7 Howitzer Motor Carriage, dubbed the Priest, was the most successful and widely used example of American self-propelled artillery during WWII. Examples continued to be used by the U.S. Army during the Korean war, and beyond, even serving Allied countries into the 1970s. Coined the Priest due to its pulpit-like structure for the gun commander, this armored fighting vehicle would see action in North Africa, Italy, and the D-Day landings in Normandy and all the way to Germany.
