Constraints imposed by the designer of a game can be more important than the limitations imposed by the "code". Taking into account the excellent (x2) job done here by Don and Andy and the other contributors I usually tend to agree with the "rejection" of various proposals which are considered to be "outside the game's scope". A word of notice though. There is a tendency by some scenario/campaign designers to increase the time scale (above 40 rounds)and map scale. So it seems to me that we are already "pushing the envelope" and at same time the "scope" of the game maybe becoming more "unclear".
Maybe it is time to discipline the troops

BTW is the (actual) timescale for unloading from tank transporters comparable to unloading barges from barge carriers?
