My my, don't be so literal please. If a joint venture was formed and a new hierarchy introduced, then the CxO of company B would still not be under the thumb of the Assistant Manager of Complaint Handling of Company A.
I just don't see what you are attempting to express with this example? As I said, whether or not the companies do a joint venture changes absolutely nothing on how staff of both companies deal with each other.
This does not apply to the context of this issue at all - if one of the companies in your example was an Inquisitor, then they'd have authority over the other party regardless whether or not they'd do a joint venture.
Okay, very simple. Organization A is a partner of organization B is a statement about organizations. Not about members of organizations. If you claim that this makes Inquisitors and KT members equals, the burden of proof is on you.
Again, you are missing the point. If the book says that "neither party is subject to the command of the other" (p. 305), then a random Inquisitor cannot just show up and "steal" a Kill-team by claiming authority. Doing so would undermine and erode the Deathwatch's independence - its equality.
Whereas, if the KT was on a mission under order by an Inquisitor, another Inquisitor cannot just show up and "steal" the KT by claiming authority because they are already "taken".
Even by your interpretation it doesn't make sense. When a Kill-team is operating under orders of their Watch Captain (meaning: every single time they are dispatched on a mission, so: always), what exactly is supposed to happen if an "equal level" of authority in the Inquisition shows up and countermands those orders?
The same thing as if they were under inquisitorial command. Either "Yes, we think we can manage to look into it" or "No, Inquisitor X, we have our orders and we cannot compromise our original mission."
Elaborate what you consider "indirect control" then, please.
Soft power. An inquisitorial request cannot be simply brushed aside by a Watch Commander, not unless it's obviously heretical or damaging to the mission. The nature of partnership and the support role of the chamber militant mandates that a Watch Commander should have very good reasons for denying a request. These are fringe cases. Normally there will be accord/comromise. Or appealing to a higher authority for arbitration.
If you didn't talk about authority, why did you bring it up at all?
This debate is about one person being able to command another, not someone voluntarily deciding to agree.
And I'm not misreading things. The book specifically points out that the effect of this Ability is based on the Ultramarine's way of thinking. In case the partial quote was not enough, I'll repeat the full description:
"The Ultramarines consider themselves a pure expression of the Codex Astartes and among the truest of the Emperor's sons. This pride and unshakable personal belief often manifests itself in their leadership abilities and the example they set to other members of the Adeptus Astartes."
He doesn't even get a bonus to the Test, he's just stubborn enough to try again. Also, what kind of bonus does a Space Wolf get to their reputation? A Blood Angel? Do they have similar Talents, given that they are from First Founding Chapters as well? According to you, they should have a similar Ability.
Of course they don't. Deathwatch isn't a simulationist game, you know that as well, so the questions are moot.
Why again does it only extend to members of Imperial forces? Not to any imperial citizen or just any NPC? Surely some xenos might also be impressed by that much confidence!
Actually, I'm not even disagreeing with a Chapter's reputation being able to influence its dealings with others. After all, this has been mentioned in GW fluff countless of times. However, you are missing a few important things:
- this does not seem to be represented in the DW RPG (perhaps for one or both of the following points)
- if confronted by a DW Marine, are random acquaintances more likely to see a, say, Blood Angel, or simply a Deathwatch Marine, because this makes up 90% of their visual appearance and 100% of their temporary allegiance?
- should a Chapter's reputation truly be known to everyone in the Imperium, or only to those individuals who have actively interacted with, been told about, or researched its history? (probably a much, much smaller number)
But again, this sub-debate is useless, because we were talking about authority and commands, not voluntary subordination.
I can tell you what an NPC sees in my game (in order of familiarity, more or less):
A. A bunch of Astartes.
B. Signs of the Holy Inquisition.
C. Various Chapter Shoulder Pads.
D. Deathwatch Marines.
Depending on the NPC's knowledge and the chapters, they recognize the chapter symbols or not. If some recognizes the Ultramarine sign but doesn't know what the Deathwatch is (quite a few people fall in this camp), he will think he is dealing with an Ultramarine.
As for how many people know specific chapters... that does not seem to be quite clear. Personally, I go with a medium amount of fame regarding the Blood Angels, Space Wolves and Ultramarines. Ultramarines go to the top slot once you deal with military personnel.
