By 1944, Zussman was serving as a second lieutenant, commanding tanks of the 756th Tank Battalion. On September 12, 1944, during a battle in the city of Noroy-le-Bourg, France, Zussman repeatedly went forward alone to scout enemy positions and exposed himself to enemy fire while directing his tank's action. Under Zussman's heroic and inspiring leadership, eighteen enemy were killed and ninety-two were captured. He survived the battle but was killed in combat nine days later.
On May 24, 1945, Zussman was posthumously awarded the Medal of Honor, the United States' highest military decoration, for his actions at Noroy-le-Bourg.
Zussman was buried at Machpelah Cemetery in Ferndale, Michigan.
