I am facing my friend in a small battle. (We dont really play points that much.)
In this battle i am of course using IG, and my friend is using Tau.
I am using 15-20 Shock Troopers, and a couple officers, basilisk and lemen russ.
He is using a Broad Side, 2 crisis, 4 stealth suits, and 10-12 fire warriors.

The field is small, and has moderate amounts of terrrain (hilld and trees.)

How do you think i would do? What tactics can you give me?
