The Imperial Guard regiments are often forced to engage in exhausting wars of attrition that last for years or even decades. Losses are inevitable, and the number of personnel decreases inexorably during the campaign, but those who survive become the most resilient soldiers of the Astra Militarum. The fire of war has hardened them into fierce and deadly warriors who are always the first to charge into battle and the last to retreat.
The Death Corps of Krieg are uncompromising fighters who disregard such concepts as retreat or surrender. They specialize in long, exhausting battles and trench warfare, and their siege regiments are renowned for their fanaticism. Additionally, individual units can carry out missions deep in enemy territory as part of the Kill Team.
