How do you keep track of which units have already moved?
Avoid unnecesary moves in the combat move phase


Belive it or not, I found out that the typical source of confusion is that most players move units that are not going to fight (nor Aircraft carriers that won't provide a landing base to attacking airplanes) in the combat move phase.

It's not against the rules but.. there is no benefit in doing so. In fact it's much better to wait for the result of the combats to know where to move.

Never doing that helps a lot: every unit that is not in a combat area, has not move prior to non-combat phase move.


  The airplane combat nightmare


This happens with japan and germany, specially in 1940 editions.  Even though you know that airplanes have moved to the combat zone you need to keep track of the ammount of movement left

There is an idea introduced I think in the revised edition: fuel markers.  Simply, have a die or any other thing that can mark from 1 to 5.  When you gather many airplanes in one zone start adding one marker for each airplane, each showing the ammount of movement (fuel) left. Separating of course each kind of airplane.

When selecting airplanes casualties simply remove the lowest fuel marker (that's called being a good captain) so you are sacrificing airplanes with the least movement.

On the non combat move phase move the remaining airplanes and each fuel marker shows the movement of any given airplane.


  Have your enemies pay attention


This is a gentlemen's game.  They can tell you what has moved and what not. They know because they are looking at your positions for possible attacks all the time

Hope any of this helps!
