After the successful colonization by the Earth Union of a total of 23 planets, the need for terrestrial transportation over rough terrain beyond unmanned systems such as MTD-205 drones increased enormously as it was no longer only people dedicated solely to explore the new worlds that would need transportation, as they now had to focus also on the military forces of CASE and the future civilians that would gradually occupy the new territories.

So the newly formed by the 2030s NASA sub division known as TUST (Terrestrial Union Space Transportation) began to improve the explorers with which they already had to support more passengers and weight while retaining its unique stability system for possible changes in gravity and atmosphere, and the incorporation of armor and modular armament for those intended for combat that CASE could serve in case of need against a new threat.

The result was an all-terrain vehicle that over the generations was perfected for all kinds of environments, the model 553 "Jaguar", capable of running both on diesel from Titan's Grejnal algae treated under fermentation in Biodigesters, and by the now common for the XXIII century batteries of Kestyern crystal fragments, both being long-lasting energy sources and not polluting for nature, the vast majority of its chassis composed of titanium and Teraformium, wheels interchangeable by light antigravity modules like those present in the Wasp aero motorcycles, a pair of LMG-70 turrets with the same ability to exchange ammunition between bullets and energy of the crystals and the most practical thing that also have their commercial versions for civilians and explorers, adaptable seats for the different anatomy outside of humans and bipedal zoosapiens, being able to fit the body of taurs, nagas and aquamorphs without any problem and without limiting the maximum of three passengers for the vehicle.

The Jaguar is currently the most used vehicle by both CASE and the standard military forces of all Earth Union colonies, having its slight variants and different armament according to the desired customization, and an unarmed version is also available to the general public for exploration and long journeys across diverse environments, which makes it the most practical vehicle for the Earth Union in current times and has helped them to combat new threats that have arisen in recent years such as the Kor'vlann, as well as helping in desperate times humans and zoosapiens to transport themselves without any impediment no matter how different they may be.
