Other question: was the arty accurate enough to give precise or did you give "windage" to make sure nothing fell in your area.
Thanks for the help and patience and service all who replyed. You may have ensured my Dad came home; who knows?
You don't give them windage. Just give them a good grid, or polar plot, or shift from a target reference point, and they will put it where you told them to put it. Infantry is the Queen of Battle, and the reason Artillery is King is because Artillery puts the balls where the Queen wants 'em.
There are occasional short rounds, but there isn't much you can do about them.
