In Action!

Here's an example of my 20 Ork Boyz assaulting in on 10 Necron Warriors. You can mouse over the abbreviations to see what they mean. I've entered in all the important stats that I found on the GW website (so PLEASE do sue me for publishing your IP! PLSPLSPLS!) and ticked the appropriate check boxes, in this case I'm assaulting in and my units have Furious Charge.

Clicking the "HAMMER!" button will run the maths and spit out the results:

You have taken 2 wounds!!
You have won the close combat!  Opponent must fall back!

How d'ya them apples?! Necrons take 5 wounds, Orks take only 2. You can even see the suggestion of the number of units either side would need for a positive chance of total decimation of the other unit. In this case, we'd need 40 Ork Boyz or 48 Warriors. Intereting, huh?

An important thing to remember is that this is only going on probability. So, if you roll less then the average roll, too bad. If you roll higher, then good for you. I don't wanna hear your whining when your properly sized unit gets decimated cause you rolled 1's. Suck it up, sissy.
