We also have the small, FMG dice though they were quite expensive. A strict division of combat/noncoms is helpful.
Another method is to count airplane movement by orientation;
0: plane faces north
1: plane faces east
2: plane faces south
3; plane faces west
4; plane inverted, faces north
5; plane inverted, faces east
don’t forget that planes that have them most moves left would be lost last, so that if any fudging/goof ups had occurred, (such as having fighters with 1, 2 and 3 moves left in the same battle but forgetting which ones were which), if only one survives, it has 3 moves left.
When you do your combat moves, move the pieces furthest away first, and the closest to the battle last. This helps show what pieces can reach only one battle vs more than one battle.
When you place stacks of especially Axis units, place them pre-broken for transport. 4 men and 3 arty is represented by 3 men in one stack, one single man, 2 arty in one stack, one single arty. This avoids having to constantly break a stack that will have to be divided after setup but imm. before combat begins, which avoids muddling various stacks.
Then, during noncoms, move the pieces furthest from the battlefront first, finishing with the units closest to the front.
Clean game.
