In this Death Korps Diorama at Warhammer World were various heavy tanks and infantry.
Across the diorama was infantry and a fair bit of snow.
This Malcador Infernus was part of that diorama.
The Malcador Infernus is a variant of the venerable Malcador Assault Tank design. It is not widely used by Imperial armed forces at the present time and is in fact little known even within the Imperial military.
