okay thanks, I feel that makes a lot more sense. So the maximum possible combat would be each side throwing 30 dice per stage per side (assuming the force was large enough) = one round of combat
How to leverage biding for turn order
The Allies can leverage the Axis into bidding more than they want for turn order by every turn they trade (USA/UK/RUS) 5 OSR for 2 OIL from Venenzuela or Suadi Arabia.
Thus the Allies every turn get 2 oil which they use to bid for turn order, they do it every turn no matter what, that will force the AXIS players to bid at least 3 oil every turn if they want to dictate turn order.
Do not overlook the power of bidding and how it effects the orders and production. The Allies need to leverage their universal access to oil over the Axis, who have no access to oil at the start of the game.
