Welcome to Librarium Online!
Well, I haven't actually played a 40k Battle, so a LOT of this is theory. I have looked over other armies and a few Battle Reports. Here we go:
Shas'el Crisis Suit Commander
2 man Crisis Suit Team
-Twin-linked Missile Pod (both)
-Targeting Array (both)
-Devilfish (will donate to the second Firewarrior Team)
2 man Broadside Team
-Advanced Stabilization System
-Linked Burst Cannons
Totals 1000pts exactly.
I'm open to suggestions. I planned on using Stealth suits, but couldn't fit them in. The Pathfinders replaced them. I'm kind of upset that I couldn't fit in any shield drones or such, but there's not much I can do about that. I'd like to keep the Firewarrior Teams at ten each. Aside from that, the only thing that I'm worried about is the lack of Kroot (and therefore I'm dead once I get Meleed). If I could include them, using a few hounds would certainly be included.
surely a stealth suit team or a near full kroot squad could get you another two hundred points?
if its a bit less then help yourself to shield drones, and 1200pts is a nice number to play with
