This web site takes care of all the rolling for both the sides:http://dicey.net/login.html
You simply plug in your e-mail address and your opponents. Next, you plug in the territory you're attacking, your units and your opponent's units. Then, Dicey rolls for you and e-mails the results for each round to both you and your opponent -- simultaneously. You way to cheat.
You will also need to download MapView and the A&A module for it.
Here is the link for MapView:http://www.motcreations.com/downloads/public/mv_1_2_16_full.exe
This is the A&A module for MapView (which you will need too):http://www.aamc.net/files/aaav2a.mvm
This should get you started!
