The Vurtan Empire is the Imperium? Yes please.

Whiel Cattan's forces would be various anthromals and some humals. Mostly smaller/weaker species, like [url=http://fc09.deviantart.net/fs70/f/2013/043/f/a/13_02_12_badgerines_by_zazb-d5ur3dm.jpg]these badger warriors[/url], because large species like bears and elephants are likely to be player-controlled elites. They may have more modern equipment as well, but i imagine most prefer melee weapons due to their physical upgrades. Plus it fits their theme.
