- "The 80th only moves forward, just like our motto says."
- — Lucas Gibson
Before the war, Lucas Gibson worked as a coal miner in Virginia. As mining was a vital industry for the war effort, Gibson could have gotten a draft deferment, but decided to enlist in the US Army anyways. As a soldier of the 80th Infantry Division, Gibson fought in the 1944 camaign in France. During the German counteroffensive at the Battle of the Bulge, Gibson's unit advanced into Luxembourg to cut the German supply line at Ettelbruck on December 23, 1944.
During the mission Ettelbruck, Gibson's squad under Sergeant Mason fought house to house to clear the town, facing German troops, trucks, and tanks. Gibson was knocked down by a Panzer shell, but was saved by a Sherman from the 4th Armored Division. After securing Ettelbruck, Gibson and the 80th Division took part in the drive to relieve Bastogne, Belgium, but is himself not seen in the level The Race to Bastogne.
After the Battle of the Bulge, Sergeant Mason's squad pushed into Austria to capture Braunau am Inn, Adolf Hitler's birthplace. While crossing the Inn River on February 7, 1945, Private Gibson and the others were ambushed by Germans and had to clear out the town. Fighting through an extensive underground bunker, Gibson's squad found a launch site for the V-2 Rocket. Though the Germans launched one rocket, Gibson was able to destroy the second using an explosive charge. For his actions, Mason recommended Gibson for the Distinguished Service Cross.
