War machines such as Empire Great Cannons, Orc Rock Lobbers and Dwarf Bolt Throwers are powerful units on the field of battle, able to pulverise whole regiments, breach stone walls or even slay fearsome monsters with a single, well-placed shot.

War machines form a distinct troop type. However, as their rules are rather unusual, and cover many different weapons that can be found in the Warhammer world, they are dealt with in their own chapter later on.
