Well my army list was as follows, all had frag grenades, infiltrate, and acute senses.
10 man squad with 2 plasma guns, and a power fist, plasma pistol sergeant
8 man squad with 2 melta guns, and a power fist sergeant
8 man squad with a flamer, and a power sword, plasma pistol
1 librarian with bolter-melta gun, about 200 points with add ons
2 land speeder tornadoes with AC, HB config
6 terminators with 2 assault cannons
1 vet dread with flamer-fist, and assault cannon
2 missile launchers 2 heavy bolters in a dev squad
First opponent was ultramarines in a recon gamma and it was a pretty even fight until he was able to claim double points in the bottom of the 6th turn with his assault marines and win by the 285 points bonus for being in my deployment.
Second opponent was a very heavily armored space wolf army in a seek and destroy alpha mission, I only had 1 squad of flamer marines left after his 4th turn and he was relatively intact, he used 2 squads of long fanges with PC, LC, HB, Hb and the other was PC, PC, LC, LC, he also had a crusader as a transport and 2 vindicators, and 2 razorbacks, I only got a bye giving me a draw because he was forced to leave do to parental interference.
Third opponent was a 32 terminator army from the dark angels in an omega cleanse mission, 1 command assault squad, 2 cyclone squads, 2 AC squads, and 1 mixed squad. I was left with one squad at the end of the game with her claiming the other 3 corners, dusk till dawn didn't happen, and she won first turn and was able to decimate my terminators and killed my dreadnaught in the same turn it came in with 10 chain fist hits, :(
