Order of Battle for the 83rd Catachan during the Battle of the Heretic’s Ambush

My 2000 point list for an upcoming battle:

Colonel Trakken looked over his officer's reports.  The heretics were coming and high command demanded that they be stopped.  No matter the cost, the heretic Space Marines and their misguided Valhallan guardsmen must not be allowed to escape.

He looked at his forces that were available:

He had sent a Patrol Detachment ahead of the main brigade force. It was composed of:

++ Patrol Detachment (Imperium - Astra Militarum) ++

The "priest" invited himself, and spoke in some gibberish whenever he was questioned.  It's clear he understands what we say, but the only intelligible things he says are the crudest profanities.

Let me know what you think.  Too many mortars?  Not enough?

I'll publish the battle report in another post.  Victory  to the bold!
