In Dawn of War, they use troops that are corrupted mirrors of their loyal Imperial counterparts. The Chaos Space Marines are traitors that, ten thousand years ago, chose to abandon their duties to humanity, betray the Immortal Emperor of Mankind and the Imperium, and instead worship the Gods of Chaos, accepting promises of power and immortality.The Space Marines are the only playable race in the single player section of the game, and the 11-mission campaign features the 3rd Company of the Blood Ravens chapter as the protagonists, led by Captain Gabriel Angelos and Librarian Isador Akios. Their troops and vehicles are more expensive, however, reflecting their limited numbers. Space Marines have the highest morale in the game. Inducted at a young age, each Space Marine receives biological modifications, a lifetime of rigorous training, and lives to experience centuries of endless battle in the defense of humanity. Space Marines are the elite, highly skilled and genetically modified superhuman soldiers of the Imperium.Warhammer 40,000: Dawn of War features four playable armies: You can give commands normally while paused, and they will be executed when you unpause.Main articles: Space Marines (Warhammer 40,000) Chaos Space Marines Eldar (Warhammer 40,000) and Ork (Warhammer 40,000) If you have trouble micromanaging your army fast enough or don't know what to do, remember you can always Pause and think for a minute. Use this to your advantage and don't keep your own infantry in a single big bunch. Even if the actual damage inflicted were minimal, this will prevent a squad from firing and render them quite useless. Some attacks - like artillery fire or the melee attacks of certain units - knock infantry units down and send them flying all over. Run away until the enemy squad switches its target, then stop the dancing squad to fire upon the enemies while you run away with the other. If the enemy tries to melee your ranged squad and you cannot screen, move away the targeted squad while you shoot at the enemy with another squad. Then use your ranged units to help out the meatshield squad, otherwise it could lose or be severely weakened. To prevent an enemy melee squad from reaching your ranged units, you should have a melee squad of your own available to intercept. If the enemy squad is really hurting you and you don't have anything better, order one of your own ranged squads to charge and melee them. They will be unable to fire, and probably lose to your melee squad anyway, although you want to pepper them with ranged units for good measure if possible. To prevent a strong ranged squad from using their most effective attack, send a squad - preferably a fast-moving melee specialist squad - to engage them in melee. See the army descriptions for details on using Space Marines and countering enemy units: You have to build your army according to what the opponent has, choose which units will be in front and which will flank or hang back, and you must see that your units choose targets they are effective against. You can't just build random stuff and send it to the enemy base they will get slaughtered. Strong ranged units tend to be weak in close combat.
Anti-vehicle weapons are good against vehicles but bad against infantry, and vice versa. Many units and weapons in Dawn of War have a specific role. This guide will not explain things that are already clearly described in the tutorial, such as Requisition, Power, Squad/Vehicle Cap, Strategic Points, reinforcing squads, et cetera. The tutorial will teach you the basic gameplay mechanics, the role of your backbone units, and what you will need to get the different units/structures. It may sound stupid, but you really should. On the other hand, some multiplayer fundamentals - such as build orders and early harassment/rushing - are of no consequence in campaign play. There are some generic tactics and techniques that apply regardless of the mission or the specific units in play.
