So would it be considered NCF if there were a similar force, like Ultramar Auxilia, operating within a few systems as purely a mobile defensive force? Not supporting the Chapter on offensive missions but reinforcing planets under siege within the region.

Even without a Chapter, purely a human controlled region, lets say a system the size of the Sol System for example. With the great multitude of rights and types of governments ruling under the High Lords of Terra, isn't it likely that systems would have a centralized government and therefore maintain a "System-Auxilia" separate from the Astra Militarum Tithe?

From reading the wiki, a single planetary governor can be lord of up to an entire sector in the most extreme cases. Wouldn't it be most efficient to have a single military force defending the sector in question compared to having each governor provide the defenses of his world? A centralized sector/sub-sector/system defense force would allow the uniform armament of the region's PDF/Auxilia and allow an easy reallocation of resources, manpower, and leadership should the tides of war engulf it.

Given the decentralized nature of the Imperium and how planets and regions of space have entirely different rights and regulations based on ancient treaties, real or forged, it could be argued that regions of space, especially along the fringes of the Imperium, would have an "Auxilia Defense Force" that operates across planets.

Though, the reasons such a defense force should be explained well and given good reason to exist.

(I personally have an article about an "Auxilia"-like force, so I am biased. I am currently working on it and need to change a lot about it. However, I believe it should be allowed because of the nature of the Imperium. Reading the Wiki, the Great Crusade brought over 2 million human settled planets into the Imperium. There must be realms subjugated during that time or emerged since then that span multiple planets and still maintain a sense of autonomy/centralization. I believe that it would make the most sense for such regions, some of them at least, to maintain a cross-planetary defense auxilia force.)
