Bestiary: Battlecows

Bred for war by the U.S. government, the Battlecow was ultimately deemed a failure due to the fact that their innate bovine docility was impossible to overcome regardless of how much armor plating and large-calibre ammunition was grafted to their genetics. They're also poor as livestock due to the fact that their tank treads tend to make a distaster out of any pasture they're given to graze, their milk is toxic due to the depleted uranium used in their cannon shells and their meat has the taste and consistency of C-rations.

They are, however, excellent for tilling fields, combining the best attributes of tractors and oxen in one convenient package.
