Tactical Invasion

The main strategy in the game is to use cover and flanking. Soldiers sitting behind a tree or a rock will get less damage than soldiers without cover. This
can be a problem if enemy has a good position and good cover.

The way to overcome enemy cover is to use flanking. This means attacking from multiple  directions at the same time. Cover is most effective only towards the direction that the soldier is facing. So two soldiers facing each other will get full cover, where as attacking from behind will negate any cover.
