build is fun, finished product is good for display, way too fragile for play. NOT an American light tank! This is a Soviet 2A3 Kondensator AKA "capacitor" It fired 406mm / 16" (that's battleship caliber, like the US Iowa class!) atomic shells! It was made obsolete very quickly by nuclear cruise missiles. Only four of these were ever produced, one of them is on display at the Red army museum in Moscow.
