Greetings everyone.
Im currently playing/GM some deathwatch game and was wondering: since there was various types of Honour Guards (each chapter with his own definition/name), why on the book rpg there is only one(taking this name) for Ultramarine. I saw something that can resemble one for Black Templars..., but what about those from the first founding - White Scars, Raven Guards, Iron Hands, Salamanders, ... ?
I know we can House rule some and stuff..., but i was wondering, did you guys had write something of it - so we can adjust and create others? Any ideas?
Thanks for attention.

PS: sorry about some bad grammar.
