If a building has a single storey, the unit occupying it has a line of sight in all directions, drawn from a height equal to the models themselves. A number of models up to a unit strength of 5 may shoot.
If the building has more than one storey, then another group of models up to a unit strength of 5 may shoot per extra storey, and these extra models may also trace line of sight over other models just as if they were on a hill.
Players should agree at the beginning of the game the number of storeys for each building.
The range is measured from the edge of the building and all the normal shooting rules apply.
