It's a little-known historical fact that Germany and Japan deployed Rancors in both the European and Pacific theaters to fight against the Allied onslaught. While generally useful in the open battles in the fields of Europe and the jungles of the Pacific islands, their Achilles heel was found to be close quarter battles in the cities, where the Rancors were easily defeated by dropping doors on their heads. Ultimately, the Rancors were unable to turn the tide of battle in favor of the Axis, and they were withdrawn.
