Maurice Rose?
Last fall I read a biography of Major General Maurice Rose, the commander of the US 3rd Armored ("Spearhead") Division. I presume that he is the general who promises Ike the tank with the 90mm cannon. The real-life General Rose (the highest-ranking Jewish officer in the WW2 US Army) was tragically killed in action in the final weeks of the European war, in a still-controversial manner ( his peep* was cut off by a German counterattack, and he was machine-gunned by a German tank commander while attempting to surrender). Although the son of a rabbi, Rose's dogtags listed him as Protestant, a sad nod to the prevalent anti-Semitism in the US Army of the era. General Rose's bullet-riddled helmet is on display at the Patton Museum at Ft. Knox, Kentucky.
*In the WW2 US armored divisions, "jeeps" were usually called "peeps".
