An armored tracked vehicle is provided with traction-increasing grousers and a remotely controllable system for extending and retracting the grousers. In a preferred embodiment of the invention, the grousers are extended by a hydraulic system formed of a plurality of radially arrayed pistons and cylinders. Conduits for the hydraulic system are located in protected positions within the vehicle's wheel axles. Preferably, the grousers are retracted in the absence of hydraulic pressure by springs located in each cylinder. Further, the grousers are arranged to align the track with respect to the wheels. This way, the track does not have to have a heavy center alignment guide.
