Orks.
The Orks race of Warhammer 40,000 has not evolved much from that of Warhammer Fantasy Battle - they still fight crudely and depend on numbers rather than technology and strategy.
From Games Workshop[]
"A galaxy spanning menace, the green-skinned Orks are a brutal race who delight in battle and the carnage of war. Crude and uncivilised, the Orks fight in a simple, yet effective, manner - coming on at the enemy in great mobs and bludgeoning their foes to death in close combat."
