During the building of the Alaska Highway the United States Army distributed B Unit rations to the soldiers in remote location. The B unit contained crackers, candy, coffee, and sugar. The main can and the smaller coffee can were both opened by a rolling a small key along the lid. The date on the coffee can is marked 'March 1942'. Indicating that they were in fact rations for the Second World War. William Griggs, an army engineer who worked on the Alaska Highway recalls the rations. “At the Cat camp we had to carry our lunch with us. The cooks never got to us. We mainly had WWI rations that come in a little tin can. We didn't have to worry about doing any dieting.” - quote from PBS special "Building of the Alaska Highway"
