The Orks are a faction that specialize in brute force melee combat and a direct assault against the enemy. Although they do have ranged weaponry, they have shorter range compared to other factions and mostly serve to supplement their melee units which are arguably among the best in the game. Despite being a strictly offensive civilization, they can also be played defensively and can counterattack rushes from other factions. Unlike other factions from Dark Crusade and beyond, the Orks have the ability to construct an indefinite amount of turrets for defensive purposes and securing their territory. Ork buildings also have ranged weapons mounted on top of them, allowing them to resist enemy invasions more effectively.
All Ork buildings (except for Generators) act as turrets. The most dangerous ones are Waaagh! Banners and Da Listening Posts, which can be upgraded with heavy weapons. Orks need a certain amount of Waaagh! Banners to build anything but basic units and structures; the banners also raise their unit caps.
