I've got a system

ok I found a auto roller
http://www.brockjones.com/dieroller/dice.htm

it lists all your rolls then you just count how many hit, plug that in and roll damage..

I also made some excel sheets for each unit of troops, I should be able to speed things up and calculate a round of fire in about 3-4 minutes.

A couple of dry runs tells me we should do about 500hp per round = 65-70 orcs/round.

actually it would seem I goofed on the parameters , behind smoke at med range is probably closer to 300hp/round

I like it.

I did the stat roll and received the following...

18

17

16

11

10

This role will be used in my next character generation.

Cool.

There's also a die-rolling feature on this forum somewhere.
