Finished constructing the last of my initial investment. 495 point force ready for fielding in next Wednesday's Escalation League at Astral Games. I will chronicle my steps towards making this a noteworthy 2500 point, fully painted army.
Details on the specific chapter will be forthcoming, as I haven't decided much beyond a basic colorscheme (bone and dark blue). I think the likeliest would be a Second Founding chapter of the Dark Angels, or just a generic Space Marine chapter.
So far as the general tactics I'm wanting to use, I am planning on fielding very strong close-combat units (vanguard veterans w/ jump packs and dual lightning claws) backed up by a wall of bolter fire, with Dreadnoughts suppressing their vehicle units.
