Axis & Allies Combat Simulator is intended to be a helpful battle calculator/simulator for the Axis & Allies board game by Avalon Hill.

I originally wrote this because I was interested in winning percentages vs unit mixes and IPC values. Specifically mixing in Artillery, Battleships and Bombers and their effects on battles vs costs, air attack vs sea units, using Fighters as adequate defense, etc.

For instance, take a look a these 3 land battles. All 3 have the same IPC values, 35, against your generic defender (same IPC values, 30). See how the Win % changes for each sim.

Land A	Land A1	Land A2
Infantry 6 5 Artillery 3 Tank 1 3 Ave Win % 69 29	Infantry 5 5 Artillery Tank 4 3 Ave Win % 57 40	Infantry 5 Artillery Tank 7 3 Ave Win % 40 57

Or, the another interesting scenario is the below battle with Revised Rules. (Using 50th Rules is a completely different result due to Transport rules). Starting with Air 1, add 30 IPC of Fighters, or 30 IPC of Bombers. Which would you sink your money into? Fighters obviously give a better battle advantage, but Bombers have a longer range.

Air A	Air B	Air B2	50th Air A
Fighter 5 Bomber Transport 5 Destroyer 3 Ave Win % 10 88	Fighter 8 Bomber Transport 5 Destroyer 3 Ave Win % 83 15	Fighter 5 Bomber 2 Transport 5 Destroyer 3 Ave Win % 74 24	Fighter 5 Bomber Transport 5 Destroyer 3 Ave Win % 99 1

Some interesting side notes:

• The web version of the simulator was written in Javascript. The iPod/iPhone version was re-written in C++. Both versions should encompass all rules intelligently.
• When I was originally writing the iPod/iPhone version, I was nearly finished when I realized I had forgotten to put Aircraft Carriers in - d'oh!
