You can direct them to move to a specific location or patrol a set of way points. The game has two primary control interfaces. The strategic map gives an overview of the entire battlefield and allows you to see where all of your forces are, the terrain and where any sighted enemies are located. You can issue movement orders very efficiently here. The tactical interface puts you in the action in a 3D view of the battlefield.
Control is straightforward and intuitive.
Everything is at your finger tip, literally, in the form of a mouse click away. The interface is logically oriented and easy to use. As your units move they may begin to take fire, they will tell you if the see an enemy or if they are under fire. In general your units will fight for themselves, you do not need to micromanage the action, a nice point in the game design. Rather, you are more in the role of the battlefield coordinator, issuing movement orders to perform recon and move toward your objective.
