Comparing: Kolohousenka vs. Renault NC-31

The light wheeled caterpillar tank developed on the chassis of the Hanomag WD-50 tractor. The vehicle never saw service because it was deemed obsolete after the results of trials. Several vehicles, in three variations, were manufactured; three of them were supplied to Italy and the U.S.S.R. As of the time of the German occupation, the only vehicle left in Czechoslovakia was used as a monument.

The NC-2 project (commercial name NC-31) was a modification of the Renault FT-17 tank featuring a soft ride suspension and a Kegresse-Hinstin fanged rubber track. These features, along with an upgraded engine, gave an increased top speed of 16 km/h. A total of 15 vehicles of this type were exported to China.
