So there is an 1850 point tournament coming up so I thought I might just build off the 1500 list I have been using so far. Here is what I have come up with, the new units are red.

HQ:
Vulkan

Elite:
Ironclad Dread w/Melta & Flamer, Pod

Ironclad Dread w/Melta & Flamer, Pod

7x Assault Terminators (5 th/ss, 2 LC) w/Land Raider Crusader, Multi-Melta

Troops:
5x Scouts w/CCW & BP, Power Fist, Combi-Melta

10x Tac Marines w/Melta, Missile, powerfist, rhino

5x Tac Marines w/Power Weapon, TL-Lascannon Razorback

Fast:
Land Speeder Storm w/Multi-Melta

Land Speeder w/Heavy Flamer

Heavy Support:
Predator w/Lascannon Sponsons

=1850.

I am thinking of dropping the Rhino for another Drop Pod so that both Dreads can come in on turn 1... not sure yet though.
