Reading over the rules I'm a bit confused by the description for cover and concealment.
In this example I have a ranged unit in melee with an enemy model. Both models are B2B in rough terrain, which provides cover.
The rules state "in relation to the attacker" when deciding if the model has cover or not. So, if the models are B2B would the enemy model I try to shoot still get cover? I believe they would because they are still being shot with a ranged attack and their base is in the rough terrain, but I wanted to be sure.
