A system designed to control tracked vehicles. It features a transmission allowing the model to shift  between a 1:1 ratio and a 1:3 ratio for better handling on rough terrain. The dual differential system allows for better control of a tracked vehicle, allowing the vehicle to neutral steer, and turn on a curve. 

This mechanism was used in my IS-7 Heavy Tank MOC, you can see it in operation below.
