Thanks for the help stoat, I will play around with it some more and see what happens. I was aware of the requirement for the HQ spotter to have an LOS to the target but I was unaware of the minimum range requirement. It didn't occur to me that this would be an issue, I guess I figured the message would say "danger close" if the target was too close. In my Airborne Infantry days our 60's were able to be fired from the hip if need be. It was a great impromptu AT weapon.
Thanks for the help,
