THQ announces Dawn of War II – Retribution – Dark Angels, a DLC pack for the standalone real-time strategy expansion that will be available on April 6th. There are some screenshots on THQ Insider's Flickr Photostream, and here's word:

This DLC will allow fans to purchase a custom Dark Angels Space Marine chapter for use in the multiplayer game, with eight unique models for the major multiplayer units, and new colour schemes for the rest of the army.

The Force Commander will be replaced by the Dark Angels Company Master with winged helmet, the Tactical Marine squad will be in their Dark Angels robes, while the other squads will also be given their chapter-specific revisions. Vehicles will also get a make-over, with custom designs and emblems being added to differentiate them from the standard vehicles.
