A few years ago I finished reading the Horus Heresy novel A Thousand Sons and quickly started looking for a way to create my favourite pre-heresy legion to play in 40k. In the end I went with the newly released Grey Knights for 3 main reasons...
1) It was an army of Psychic Marines
2) After building a large guard army I wanted something small and elite.
3) Cortaz and Henchmen Squads allowed me to field The Prospero Spire Guard and since allies weren't available back then this was a huge benefit.
But things have a changed; The Forgeworld Horus Heresy range has expanded greatly and their vehicles are available for use in standard 40k marine armies (except Grey Knights) and I have the option to use my Prospero Spire Guard as an actual allied Imperial guard attachment.
So with that in mind I thought it might be worth considering switching to the marine codex instead of the Grey Knights. There is the option of allying the two forces especially with the one of the forgeworld chapter tactics allowing Grey Knights with an Inquistor to become Battle Brothers allies. But until the new rules edition come out in the next few months I want to hold back on the idea of using allies.
So for the moment I'm just looking to brainstorm a few ideas on how to build a marine force to suit the Thousand Sons, such as what units and chapter tactics to use, so I'm looking for suggestions?
So far I've have suggestions to use the Legion Of The Damned digital codex, or a more interesting option is a Stern guard heavy army with the specialist bolts representing small psychic buffs. Another person suggested having a small allied guard attachment and add a primaris psyker to each of the squads.
I'd be grateful for any feedback and suggestions?
