Sherman FireflyA British version of the American M4 Sherman tank, developed in early 1944. It differed from the U.S. version by having a more powerful 17-pounder gun, different placement of the radio and ammunition, no bow gun, and no driver's assistant position. Between 2,100 and 2,300 vehicles of all modifications were built from 1944 through 1945.
