I would love to see a variable reinforcement feature to randomize arrival times. In the Combat Mission scenario editor, there was a field to enter the percentage chance a new unit would appear on a given turn. I believe there was also a way change that % chance for future turns.
This feature would greatly empower scenario designers, and add a lot of replay potential for very little coding overhead.
Sure, can have a look at that. There's already variable time for naval units (once used, naval units may re-enter after a fixed or variable number of turns (or not at all). Cheers, Brian
