The only difference is that you’d be forced to hold off one turn. No biggie. 5 Bombers is 15 IPC you’re down anyway, and since it’s going to take at least a round to get into position, waiting 1 round for units to save up is nothing.
BTW, the Flames dicey is screwed up on rolling the damage. They say attacker does 3 all the time, defender does 2 or 3. I already notified them it needs to be fixed to come into accordance with the actual description of LL SBR.
Is it Axis and Allies Revised that you are trying to play?
If so, search for ‘Triplea Warclub’ on your computer. There you can download rules and files to play the game online or via e-mail.
I learned how to play on their game ladder, ( I don’t own a boardgame) and have played well over 80 games, with over a 50% win rate.
