We took my newly completed Terryn Knight Household against a Scary Ork Stompa-Dread Mob. Four Turns of Mayhem resulted.
Both sides charged straight at each other, firing all the way. The Knights shooting was overwhelming, and was able to thin out the Mob before it closed to melee. The close combat was as fast and brutal as you may think. The Stompa took out a undamaged Paladin with it's Mega-choppa (24 points of damage!) before the Knight Baron fished the Stompa off with a spectacular 20 point hit from his Thermal Cannon. The Knights took a lot of damage, but only lost one Knight and all three Armigers.
I would like to run this battle again and give the Orks a 51 PL handicap, which happens to be the price of a second Kustom Stompa...
