The planet Azeroth seemed to hold "a selection of humans, mutans and aliens in a state of perpetual superstition and conflict". the Confederacy seeing the strength of these so called "taurens" were impressed with their "super-human stamina, overpowered racial combat abilities, and bizarrely well-developed horticultural skills".

Here is the description:

"While most tauren were satisfied with their agrarian culture and primitive existence, the Confederacy was able to lure away large numbers of young bulls for a life of adventure and violence along the galactic rim. Other tauren referred to these adventurers as 'mad cows,' and they were ostracized from the rest of their kine.

The newly created tauren marines didn't care--they got neat-looking armor and big guns to own everyone else with. These beefy new soldiers are now an integral part of the Confederate military, and have managed to horn in on the roles traditionally filled by firebats and other infantry units."

Here are some screenshots of the new unit in action:
