Models inside buildings can shoot from arrow-slits, windows, doors or other openings. Up to two models may shoot from a single opening. Models on flat roofs, parapets, balconies or such-like can also shoot. Troops occupying a building do not all have to shoot at the same target, but shoot as individuals choosing permissible targets as you wish.

Models which have shot from windows or other openings in their own turn can be seen and shot at by the enemy in their turn. Models inside buildings benefit from the advantage of being behind hard cover (-2 to hit) as well as being in skirmish formation (a further -1 to hit).
