Hard cover represents cover of a more durable kind, like that offered by stone walls, boulders, buildings and suchlike. We also count intervening units as hard cover (if they obscure the line of sight to the majority of the target, of course) as their presence will play havoc with the shooters' accuracy. If the majority of a unit is obscured by such 'hard' terrain, it is said to be Hard cover. Hard cover inflicts a -2 shooting modifier. Note that the To Hit penalties for hard and soft cover do not stack – in a situation where a target would benefit from both soft and hard cover, simply apply a -2 shooting modifier for cover.
