Abstract: A tracked vehicle has a pivotable suspension. The vehicle includes a vehicle frame, a motor configured to produce power for the vehicle, and left and right track assemblies that are each connected to the frame. The assemblies each have a drive wheel configured to be driven by the motor, an endless track driven by the drive wheel, wherein the endless track has an outer side and an inner side, a bogie positioned on the inner side of the endless track, a support wheel attached to the bogie and configured to roll on the endless track, a strut connected to the frame and to the bogie, and a shock absorber connected to the frame and to the strut. The strut and the shock absorber are pivotable relative to the frame. The vehicle may have low ground pressure, consistent traction, and may be modularly configured with a floatable hull for aquatic travel.
