Thats a very good point, because you will often see the town rebuilding within, 30 mins because of the convoys, that resupply it.
If the troops objective is to destroy the map room you have to think if the map room reups with the convoys or is just set on a time limit.
I think this would be a good queston to ask and will help with finding out the time period form first to last troop, and of course if it does reupp with the convoys the time period could be very large from destroying them.
