I’ll do a little more preparation for the invasion proposal, mark III. With the rule changes I had proposed, an invasion would be frozen if the support base was insufficient to support it since no more attack posts could be made with it, but the Invasion Transportation entry still remained, so an invasion could be rekindled by adding some more population in the support base again. How about a couple of ways to deal with these lingering Transportation entries?

Add an attack method to the Conflict rule:-

If a controlled Territory is the target of another Country’s Transportation entry, its controller may use the Attack Method Repel at that Territory if the number of units in the Transportation entry is fewer than one quarter the population in the target Territory. E may then add 1 to the number of periods required to complete the Transportation and optionally transfer the Transportation entry to an adjacent Territory which isn’t controlled by a third party. The type of the Transportation then changes accordingly (Frontier Transportation if the target Territory is uncontrolled, Sea Transport if it is Oceanic, etc).

In the Transportation rule, replace “(Transportation Type): (quantity of population), (amount of periods left) periods left” with “(Transportation Type): (Origin Territory), (quantity of population), (amount of periods left) periods left” and add a subrule called Abort:-

During a Transport Session a Country may abort any number of eir Transportation entries. Provided that no other Country now controls the origin Territory, e may pay the cost of one period of that Transportation and have it immediately return home, removing the entry from the target Territory and adding its population back to the origin Territory.

Add to the Control rule:-

If a Country ever has zero population in a Territory e controls, then that Territory becomes uncontrolled.
