Warhammer 40,000: Dawn of War/Space Marines

This is a comprehensive listing of the units in the Warhammer 40,000: Dawn of War series, a series of popular real-time strategy computer games. The first, eponymous Dawn of War game was released on September 20, 2004 as a production of Relic Entertainment. Dawn of War was released to critical acclaim, and due to its popularity, two expansion packs were released; Winter Assault and Dark Crusade, on 2005 and 2006 respectively. A third expansion pack, Soulstorm, is slated for release in June of 2008.

The Dawn of War series was praised as very innovative, as it simplified the traditional resource-gathering stage of real-time strategy games by having only two resources to collect, similar to Starcraft. Unlike Starcraft's system, Dawn of War instead requires that players capture strategic locations for the requisition resource, and build power generators for the power resource. Workers are not tasked to gather resources; rather, a player must build the buildings to generate resources and defend them in order to win the game.

The first game, Dawn of War, featured four races; the Eldar, Space Marines (Warhammer 40,000), Chaos Space Marines and Orks. The first expansion pack, Winter Assault, introduced the Imperial Guard (Warhammer 40,000). The second expansion pack, Dark Crusade, introduced the Necrons and Tau. The third pack, Soulstorm, will introduce the Dark Eldar and Sisters of Battle.

Almost all infantry in the series come in squads, which may be 'reinforced'; units are added to the squad to increase its firepower and health. Also, these squads may be upgraded with better weaponry, and sometimes have special abilities, which may be innate, granted by research, or due to the inclusion of a leader unit in the group.
