Maybe some input from some Sallie players about tactics then?
As I said, Ive got some notes whuch I'll post, and one thing I had down was their combat doctrine was a mix of the Sallies siege warfare; Vindicators and such. This was drawn from the pic in Codex: Armageddon of a Storm Giants squad with a Vindicator. It seemed like the natural way to go. But its about translating that and describing how and why.
This isn't about finding what info there is on them. I have that. It's about the finer points of tactics, history. How, why, what etc and putting that in into an Index Astartes article. Obviously theres only a certain amount people can help with, and a lot of the ideas will have to come from me, but I've not done something like this before, and will need help on how to think, and how to write about it.
