Not sure I'm getting mechanics right

[Sir_Dr_D]

The manual made it sound like there was no randomness to determine if the archer hits the square he is aiming at. it is strictly a formula based on precision. If the unit you are aiming at is close it will always hit the square, if it is far it will never hit. Is that right? The precision descriptions had me confused. It sounded like we needed another command for our archers. 'Shoot at our own troops.' Only way to make sure that they are safe.

For another question that wasn;t described in the manual, how does head protection differ from body protection? When a hit is made is it some how determined if it was the body or the head that was hit, and the game uses the appropriate protection score. Or are the two protection values simply just combined into one.
