Series two rules in hand

[treadasaurusrex]

Thanks Peter for opening this discussion with a house rule governing Infantry Attacks OBA. I want to be like just you, when I grow up!

 I suggest that your proposed rule be simplified, consolidated & restated, as follows:

 Pre-plotted, off-board artillery targets may be changed every 6 turns (90 minutes of game time) at the discretion of the owning player.

Even the slowest WWI carrier pigeon, forward field telegrapher (my Great Uncle at Verdun, the Aisle, Chateau-Thierry and later at Meuse-Argonne), bicycle messenger, or mounted/dismounted courier would be able to get word of such a targeting change back to the firing batteries, or Fire Direction Control (FDC) in that amount of time if they are already firing at registered targets. I think that the guns could quickly be re-aligned and registered on the new target coordinates well within that time frame as well.
