Of course there is. I rely on a tiny microchip that was implanted into my brain when I was a child. It’s specifically designed to calculate the odds of winning Axis&Allies battles. It works on a simple principle: addition of fractions. Ha!
Please excuse the sarcasm :D , but the calculations are pretty simple. Men have a 1/6 chance of scoring a hit (they attack at one, thus 1/the six possible sides of the dice). Multiply the # of men times that fraction. Tanks and fighters have a 1/2 chance of scoring a hit. Planes have a 2/3 chance. Just add up all of those factors, depending upon what and how many units you’re attacking with, and that is the average number of hits that you should score. Decide which men your opponent will likely put behind the casualty line.
Then take into consideration the number of hits that the defense will likely score. Same thing, except defensive men and tanks=1/3, defensive planes =2/3, defensive bombers =1/6. Take that estimate of hits, and decide which units of yours would die if you did attack. Keep doing this (in your head) until it is clear who will win the battle. Perfect odds rarely pan out, so it pays to calculate a few extra hits toward yourself or round up when the defender’s hits add to a fraction.
OK, you’re right, probably quicker just to find some odds calculator. But it’s so much more fun to use the left side of our brain :lol: Good Luck.
