Here is some recorded game-play footage of DCS : Combined Arms. As you will be able to notice, players are able now to control ground forces as well in both 2 and 3D.
ED is on the verge of turning DCS world into a total virtual battlefield simulator after the release of their Combined Arms module, which adds ground operations to the already impressive set of flight simulator modules.
DCS : CA brings a whole new dimension to DCS World especially to the Multiplayer arena.
