Hi, if I don't miss anything then player units can hide behind building. You should add some occlusion or something to see if any of our soldiers are hiding this way (and what if someone attack building from behind ?). Another thing - I think you should generate bigger map and generate some kind of border (like battle map in Total War or Mount and Blade). This way graphic experience will improve because player will not see "end of the world". He just cannot move beyond border of the map.
