All melee, all the time:

Fast Attack:
10 Assault Marines, Sarge w/Fist - 215
10 Assault Marines, Sarge w/Fist - 215
10 Assault Marines, Sarge w/Fist - 215
Elite:
Ironclad Dread, Drop Pod - 170
Ironclad Dread, Drop Pod - 170
1500
If I go first, I probably get a turn 1 charge with the scouts, due to infiltrate, scoutmove, and fleet. If I go second, the scouts and a squad of Assault Marines will probably infiltrate (Shrike goes with assault marines either way).
I originally had the Dreads with Ironclad grenade packs, a heavy flamer, and had them footslogging to make a three waves of threat sort of thing (Scouts could charge turn 1, assault marines turn 2, and the ironclads getting there to mop up anything else), but I decided to give them drop pods to go with the fast and hard theme going on.
