A massive horde of Orcs storm off to battle at the behest of their Warboss.

Orcs live to fight. For an Orc, there is no greater joy than to be in the thick of battle, where the biggest and meanest warrior carries the day. Such belligerence is both a strength and a weakness, as it means that Orcs expend much of their energy fighting among themselves rather than against a slightly more distant foe. Smaller and more nimble than their Orcish cousins, Goblins have a more developed sense of self-preservation. They are cunning rather than strong, and tend to leave the serious business of fighting to the Orcs. Goblins prefer to guard the rear of an army, though in desperate circumstances they'll finish of an enemy so long as it has been given a clobbering by a mob of Orcs.

There are many varied subspecies of greenskin. Night Goblins live in the deepest caves, venturing out into the light of the sun only when suitably fortified by fungus beer. Forest Goblins prowl the gloomy forests of the Empire, and Southland jungle canopies reverberate to the steady pounding of Savage Orc drums. Most notable and fearsome of all, Black Orcs are 'ard as nails and inevitably take over any tribe they join, where they leave a trail of butchered and dismembered rivals in their wake.

An Orcs & Goblins army will often contain a vast array of different troop types, from the wide variety of greenskins themselves to monstrous beasts such as Trolls, Giants, and Giant Spiders. While Orcs prefer to hurl themselves into close combat as swiftly as possible, Goblins bring a lethal array of sneakiness, such a foolhardy Doom Diver Catapults and mushroom-fueled Night Goblin Fanatics.

Commonly, an Orc & Goblin warband will sweep into a village, slaughter the inhabitants, and charge on, pausing just long enough for the warlord to make a really big pile of severed heads and sit upon it while declaring his dominance. Terrifying and brutal as this is, it is when a Waaagh! is called that the Orcs become a truly dangerous force.

A Waaagh! is akin to a migrating invasion, when some successful Warboss throws everything he's got against his chosen enemy, and all the other Orcs and Goblins flock to join him. A Waaagh! is truly a sight to freeze the blood — an unstoppable sea of green-skinned monsters swarming across the horizon, whooping, jeering, and yelling their barbarous war cries. Few things can stand against such a force.
