Captain Tied Flanks of the Ultramares must lead her space marines into battle for the glory of Harmony and the Princesses on a forge world besieged by hogz and dogz and gretchin. It's a common set of foes that shouldn't be too much of a problem, except for the fact that there's several million of them and a significant percentage seem to be carrying weapons looted from space marines they've killed.

Just another day at work for Tied Flanks.
