This meant that each squad was a significant investment, not merely pawns to be casually rushed towards the enemy as in so many other RTS games. The Warhammer license was not superficial but had an impact on how the game actually played: the production of squads as opposed to individual units, determining what gear they have, whether a commander unit is attached, and so on.
Moreover, it provided an opportunity to amass the Warhammer armies that would be ruinously expensive in cost and time to amass in real life. The original Dawn of War was an excellent contribution to the RTS genre, combining traditional mechanics with some invigorating changes that promoted squad battles over macro-style management thanks to the innovative control point system.
