After enlisting on February 16, 1943, in Pittsburgh at the young age of 19, Brown was assigned to the 30th Infantry Division in the 120th Regiment. They had arrived on Omaha beach on June 16, five days after D-Day, to help fight in the Normandy Campaign. They had assisted in the capture of the Vire-et-Taute Canal and crossed the Vire River on July 7. 

Unfortunately, George Brown had died on July 19 in an skirmish to help advance U.S. land. 

The 120th regiment continued to fight throughout the rest of the war, helping to secure Paris, Rhineland, and Central Europe campaigns.
