Privateer Press have posted a preview of the Warmachine Mercenary Horgenhold Artillery Corps miniatures.
From their website:
The clan lords of Rhul viewed the advent of artillery among the human nations of the Iron Kingdoms with amusement. The Rhulic Moot has traditionally taken a dim view of mercenary operations, but in recent years the profits certain clan lords have gained is difficult to dismiss. Certain provisions were made to allow Rhulic mercenaries abroad to equip themselves with siege cannons and other weapons of war. Their powerful mortars are extremely destructive and can be fired indirectly, giving the Rhulic army an intimidating ability to control the battlefield.
