I believe the lascannon took the monolith and a sponsoon-mounted Storm bolter took the lord or something. I could have it wrong, I was playing the above Tau game at the same time this game was going on. I could be wrong about the storm bolter, although I was under the impression that if a tank dosen't move it can fire 1 turreted weapon and full defensive weapons, I thought only ordinance restrictred the use of defensive weapons on a stationary tank.
Oh but a funny story:
On the opposite end of the spectrum. One time my GK Grand Master and retinue took 2 full squads of warp spider rounds, a barrage from a Land raider crusader and a full fire dragon squad barrage in 1 turn and didn't lose a single man. (Me and my buddy who played space wolves took on two other friends who played eldar and dark angels).
