Dreadquake Mortar (otherwise known as the Dreadquake Rocket Artillery)
This model started life as an oversize Earthshaker Cannon conversion (with the Hellcannon body swapped out for a V2 rocket). With the release of the Dreadquake Mortar rules I saw an opportunity to repurpose the model, so added the Slave Ogre and the Russian Alternative Slavemaster (Dwarf of Fire Canyon 4). The other crew are the FW Gamesday Hellsmith, and the FW Deathshriker Rocket spotter.
