Autocannons center is in their southwest cell

[Wanderer_joins]

There is no cover possible for autocannons from North and East directions.

On the other hand from South and West directions they can benefit from.

It's the same thing with mortars (interaction spot S-W by default) but we can rotate them.

Another outcome is that the shot range is measured from the southwest cell.

EDIT: Willing to accept it as is. Thanks either way.
