for AA50 i have developed this. My feeling is the map has alot more territories, and it would take longer to play because of this. To facilitate a quicker result this was playtested and works.
Strategic Movement:
Each player’s capital territory has a value equal to half its IPC value, which can facilitate additional movement of a players land forces. Every time the Home territory is bombed by SBR the total movement of Strategic Movement is reduced one point for every 2 points of damage to the home factory.
For example: Germany has 5 SR points because it has a 10 IPC home territory. If it was bombed for 5 points of factory damage, you could now only move 2 land units by strategic redeployment.
Procedure: after placement move one land unit a total of 2 additional spaces for each SR point. Units moved can be newly created units or units involved in combat or any unit whether it moved already or attacked. Units can even move across one sea zone to another controlled territory as long as you control the sea zone with one warship.
Repair of damaged factory also changes this value depending on current damage or investment for repair.
