The Tatra factory in the Czech Republic has for a long time been building heavy cross-country vehicles. The Tatra 813 8 x 8 heavy truck has been built since the late 1960's. It was used by various Warsaw Pact armies, as a truck and as an artillery tractor. It also served for many civilian purposes. With its excellent cross-country mobility, it is also a favourite at truck trials.
