The urban damage tiles are 200 m by 200 m squares on the map where the scenery (trees, buildings etc) can be damaged. SEOW keeps track of all locations of combat and sets the corresponding tile damage levels appropriately. That means when you fly low over a village where some combat has occurred you will probably see wrecked houses, burnt trees etc.
