オイ車 mi-to
The O-I Super Heavy Tank was a prototype [[tank]] developed by the [[Imperial Japanese Army]] in [[World War II]]. The vehicle featured a multi-turreted design and an immense weight of 150 tons, second only to the [[Maus (tank)|]]. While stronger than any available Japanese tank at the time, it's immense weight and size made it unfit for the Pacific theater, with only one turret-less prototype being developed for trials.

While only the O-I was produced, this tag can refer to the variety of paper (albeit later confirmed fake) design related to the O-I popularized by [[World of Tanks]], including the O-I Exp., the [[O-Ni (tank)|]], the [[O-Ho (tank)|]], etc.
