Ok, to clarify:
There is a unit in Codex: Space Marines called the "Ultramarines Honour Guard" in the back, right before Marneus Calgar. That is the one you can use if you are playing an army from just the Space Marines Codex, with no Divergent traits whatsoever (because they're supposed to be Ultramarines).
There is a unit in Codex: Blood Angels called an "Honour Guard" which is much different. The Honour Guard is the Blood Angels version of a command squad. They can have jump packs and all other sorts of nasty stuff.
So: if you are using rules from only Codex: Space Marines, then you make take an Ultramarines Honour Guard, but not an Honour Guard. Conversely, if you are using the rules from Codex: Blood Angels, then you may use an Honour Guard, but not an Ultramarines Honour Guard.
I figured color-coding might help keep the different units straight, since their names are so similar.
