Thor’s obedience and alertness was credited with saving the lives of the Marines in fighting against the Japanese in Bougainville. Although there is not much documentation of Thor’s specific actions during the war, he will always be remembered as a member of the 1st Marine War Dog Platoon’s messenger unit.
