Starting with a POD no later earlier than 1913, your goal is to arm one of the major combatants of the Second World War (Germany, Japan, Italy, Soviet Union, US, or British Empire) with the most atypical combination of weaponry possible.
But the weapons systems chosen have to be PLAUSIBLE. You can't load down an army with kugelpanzers and glider-tanks. Even normal (but fringe) weapons systems are fine if used in unusually large numbers. A 1939 Italian army equipped with 8-inch Japanese-style rocket-mortar tubes, Gurkha kukris, trench shotguns in lieu of submachine guns, and the like, would still be pretty weird.
