The interface isn't the most intuitive, but do give this game a try. Start by following one tank around and mastering the view controls, then move on to issuing orders.
If you setup a mission in the editor where you have a tank and the enemy is on the far side of the map with only a rifle platoon, you'll have time to practice without heavy combat getting in the way.
The key controls to master are the zoom ones (quite tricky) and the follow-unit one. Once you've got that sorted, the others are easier to execute.
It's a steal for $30 and by far the best game of this type I have played - ever.
