The "Trado III"-suspension could be fitted with a track on the lines of the Kégresse track, changing a vehicle into a half-track. The first project, the "Pantrado 1", envisaged a very long type with a good trench-crossing capability, brought about by applying the principle of the articulated vehicle: it was to consist of two fully tracked truck hulls attached back to back, connected by a large horizontal articulated cylinder. The full track was to be achieved by extending the track over the rubber-tired front wheels. The cylinder could be split, creating two tanks, each with the engine in front and the fighting room, crowned by a gun turret, at the back. This type remained a paper project only.
