Dawn of War 3 Factions Guide

Space Marines

Space Marines in Dawn of War 3 have a lot of units and roles from every barrack. Assault Marines are highly recommended for combat as they have the highest early game HP and DPS in the early game and are guaranteed to send the enemies running for the hill with their leap ability.

The Dreadnoughts, on the other hand, also have a lot of HP and heavy armor damage therefore, the combination of Dreadnoughts and Assault Marines can become deadly for the enemies. Don’t forget to use the Slam Ability which stuns the opponent and allows you to avoid being ganged up on.

For support, use Predatory Destructor Tanks as they give a big advantage to Space Marines at long range.

Since we’re talking about tanks, we have to mention the artillery-striking Whirlwind Tanks. These tanks are mostly used for destroying bases and buildings.

So have some of these in your team and clear the area by bombarding enemy resources.
