@model40 What's bad is there is probably another 100 or so in this hole that we have yet to dig.

Hi,
I just would like to have a further information about numbered buttons : is it true / or possible that they were quickly outlawed as information was available to the enemy from seeing these numbers?
Thus the ennemi could know how many compagnies were on the field in the case they captured a soldier...
