Metal Cavalry

A beautiful unspoiled nature - a lake surrounded by mountains - that's a perfect place for relaxation you can say, but not here, here's a war going. You are a soldier operating in a tank unit. You are standing against overwhelming odds enemies right now, your every step must be short and quiet. Of course you have the fear but fulfillment of order is more important, you must destroy all enemy units. Can you do it? Have fun.
