Hello kalivann,
This has got to be homemade rules. It's not GW or Forgeworld and the models shown I've seen before when googling Tu'Shan for my own research. You can see the
Mr Tu'shan conversion here.The rules look a bit silly to me, they are overpriced for the honour guard to try to fit in extra 'fluffy' options.
Whilst I think that most of the options here might be fitting for the salamanders I do question the idea of a combi-flamer that can fire throughout the game, extra scoring units, eternal warrior, better invulnerable saves and silly expensive honour guard.
The marine codex is good enough at representing a Tu'shan without deciding you want He'Stan's chapter tactics (which he has because he's forge father). My plan is to take a chapter master with hammer, artificer, combi-flamer.
