What didn't make sense to me is. If Greg's trebuchets had a range of 2? And Nappy's arty had a range of 3, why didn't nappy just move his arty up to provide covering fire? Greg would have had to either charge in to try to make it to the arty (allowing nappy to move his units up to kill) or taken arty fire and been forced to retreat.
Instead Nappy left it on the hill.
Also does being on a hill extend range?
Assuming that artillery does not have "indirect fire" then while it can shoot 3 it can only see 2 unless it is on a hill or firing onto a hill.
Makes American artillery quite powerful since they will be able to see 3 by default.
I do recall hearing Greg mention that artillery does have indirect fire as an ability in which case the AI was just being thick by not moving it closer. Though, in fairness, at the time the artillery appeared on the battlefield the rifles where pretty much gone and there were no units, at that point, near Suez or even in the peninsula (probably 'cause they were out destroying Siam). The units in the area were more for harrassment than anything else.
