Three light divisions were formed, in response to combat experience in 1942 and 1943. The 10th Light Division was formed as a light division specializing in mountain warfare, the 71st Light Division as one specializing in jungle warfare, and the 89th Light Division as a light truck division. Theater commanders were lukewarm about the concept. General MacArthur felt that they had insufficient firepower, and they performed unsatisfactorily in training maneuvers, so the 71st and 89th were converted to regular infantry divisions. Despite its jungle training, the 71st Infantry Division was rushed to Europe in response to the German Ardennes Offensive. The 10th remained a special mountain division and fought as such in Italy.
