On December 16th 1944, Jennings was among a unit led by Sergeant Hall and Lieutenant William Holt, an American agent with the Office of Strategic Services, as they assault the villages of Krinkelt and Rocherath. They must fight off a counter-attack once the town is secure.
Later, in January 1945, Jennings participates in the assault on the secret German weapons facility commanded by Graf von Schrader. Jennings joins his fellow soldiers in laying down a base of fire while Holt infiltrates the facility and kills von Schrader. Holt then drops the bomb back into the bunker, destroying the complex and killing dozens of German soldiers.
Jennings may be killed during his appearances. His status following the battle, should he survive, is unknown.
