One of the more-popular Imperial Guard groups is the Death Korps of Krieg. I've always loved how they look, with their trench coats and gas masks. It's a very WWI-feel to me, which I think is awesome, since I think that war gets overlooked a lot more than it should. Anyway, there's some new units, some new cavalry, and several new artillery companies available to order for your 40k
games from Forge World.
From the release:
The true strength of the Death Korps lies in its grim foot soldiers, the ranks of disciplined and relentless infantry that make up the korps of the siege regiments. Their cold hearted courage and sinister aspect have made them among the most famous and feared of all the regiments of the Astra Militarum.Source
