My understanding of the flow of the game follows. Please let me know of my misunderstandings.
Please note that bold type indicates new material.
1. Players submit instructions.
2. a. Income from provinces. Capitals produce 2 IP, other provinces produce 1 IP.
2. b. Purchases
2. b.i. Units
2.b.i.a. Infantry cost 2IP.
2.b.i.b. Cavalry cost 4IP.
2.b.i.c. Gliders cost 5IP.
2.c. New unit deployment
Units have unlimited range within controlled territories. The presence of an enemy unit in a friendly province does NOT stop the movement of friendly units through the province.
In each province with units from opposing sides:
4.b. For each side, a morale die roll to modify the combat die roll
4.c. Pair off opponents. Unpaired units are reserved for later use.
4.d. Roll a die for each opponent in a pair. Add the modifiers to the result, and remove the unit with the adjusted lower total.
4.e. If there are still opposing units, the side with fewer units’ pair off with the reserve units. If there are no remaining reserve units, combat ends for the province, else return to step 4.d.
4.f. In the case of three or more mutual enemies in a province, it depends upon who ordered what attack. If the two ordered an attack on one, then the two attackers would not battle and if the defender is destroyed, the attacker with the larger army takes it. If A attacks B, B attacks C and C attacks A, then... how about each battle is calculated as if each army were at full strength, then the combined results from each battle are dealt to each combatant- makes sense, considering the massive chaos of the battle.
