War Beasts are a class of unit. All of them are powerful and dangerous units and many of them are heavies. Some are humanoid in form, but none are sapient. In addition, many of them also have to be physically restrained when not in battle, which may be indicitive of a low obedience; which in turn may cause them to either attack without orders or pose a physical danger to their own side. They radiate malice and hostility and it is extremely difficult to get them to stop fighting once they have engaged in combat. War Beasts are frequently used as shock troops due to their ferocious combat capabilities. Due to their long production time, high upkeep and the inherent difficulty in controlling them, even sides that pop them do so sparingly.
