After a bit of brain storming and looking over what I have, I came up with the following list. I present it to you now for consideration.
Space Marine Chapter Master -- 170 pts.
Space Marine Chaplain -- 125 pts.
Dreadnought -- 125 pts.
1x5 Terminators --230
1x10 Man Tactical Squad--205 points
1x10 Man Tactical Squad--255 points
--Razorback (TL Lascannon)
1x10 Man Assault Squad -- 215
Whirlwind -- 85 points
Land Raider --250 points
Predator -- 190 points
The way I see it working out is I'll have the Chapter Master joined to the Terminators inside the LR to go forth and kill what they can. The MM Tac Squad in the Rhino will go hunting, while the Razorback Tac Squad will set up as a kind of forward fire base. The Whirlwind will be set up to start smashing hordes, with the Predator tooled up for support, hopefully from behind cover. The Dreadnought will mainly be used as a hunter/distraction. The Assault marines, finally, will be paired with the Chaplain and used for interdiction. I plan to keep them behind cover/out of line of sight until they're in a good position to ruin somebody's day.
Feel free to let me know what you think!
