Salamanders and Dark Angels verus Imperial Guard

So its saturday. Dad and I went to the bunker and Dad was going to play Jeff, but since I wasn't playing anyone we did 3000 pts for each side. Salamanders(Me) teamed up with Dark Angels (Dad) against Imperial Guard (Jeff). 1500pts from Salamanders and 1500pts from Dark Angels and that equaled 3000pts. Jeff had over 200 models for 3000pts. I think we had about 100 models. The mission was Capture and Control that is the one with one objective in each deployment zone and the deployment was pitched battle. Make long story we won, Dad captured Jeff's  objective with his with Deathwing Terminators and Belial and Vulkan flamed a guy to death. We still had our objective with 1 troop and 3 razorbacks. Jeff was close of reaching the objective, but then he would have to blow up the tanks and kill the 5 man squad.
