You are thinking something like the Ebon Keshik that guards Strana Mechty and the Great Father's tomb on his McKenna?
No, not ceremonial or police.
The implication of the existence of an ilClan is not just that some Clan reached or holds Terra. Per the Wolf Clan SB, the existence of an ilClan implies that there is a new Star League.
If so, then what units comprise the new Clan “SLDF”?
I don’t think there will literally be another “SLDF” with “Royal Divisions”, etc.
But I don’t think the ilClan’s touman or frontline galaxies alone would serve the function of the old SLDF.
I think a Clan “SLDF” under the ilClan/3rd Star League would have to be broader than that.
Which is even assuming the other Clans will recognize the ilClan's supremacy...
IF a IS Clan becomes ilClan, I suspect none of the other Clans are just going to roll over and be absorbed. Its a empty title, like being "Kerensky's Clan" or current figurehead monarchies. You are the King/Queen but that means nothing like it did hundreds of years ago.
There may well be inter- and intra-Clan fighting over the ilClan-/ilKhanships. But I doubt that a major, lengthy, and long-awaited product like “ilClan” would be produced and titled as such over an empty figurehead.
After events like those in WoR or the revelations about what Nick Kerensky did to the Wolverines, it’s easy to jump to the conclusion that any Clan will fight any other Clan tooth-and-nail over the ilClanship and die trying.
But the reality is that canon Clan history is also replete with long episodes of very limited and ritualized warfare driving the major decisions in Clan society. Clanners have stuck to the results of their trials before, even when they didn’t like them. They may do so this time, too.
There are also episodes in Clan history where one Clan, usually Wolf because of the Founders, has been afforded privileges the other Clans do not enjoy. And there are episodes where the Clans acknowledge and work under (sometimes through gritted teeth) the leadership of an ilKhan. They may do either or both this time, too.
There are also episodes where the Clans have united against a common foe, like the Wolverines or the Society. They may do so again in the run-up to the creation of the ilClan. There are a number of potential foils: Mad Malvina and her Mongol Falcons, Stone if he goes cryo-crazy and the Republic elements that follow him, or even a surprise visit from whatever the Homeworld Clans have evolved into.
Lastly, how many Spheroid Clans even care about pursuing the ilClanship anymore, nevertheless are willing to risk their existence on securing it? The Bears? The Foxes? The Ravens? The Horses? Only the Wolves and Falcons seem willing to fight for the ilClanship. As long as the ilKhan doesn’t do anything stupid, the rest may be more than willing to join a federated Third Star League under an ilClan, especially if it means coordination/support in defeating the Houses on their borders, better worlds, better trade, better tech, etc.
I’m not saying any of this will happen. But I am saying that there are well-grounded options for the ilClan storyline to be something other than “the Clans beat each other senseless over nothing.”
My own sense is that the Wolves have been laying groundwork with some of the other Spheroid Clans that will help secure the ilClanship for the Wolves — like the cooperation implied with the Horses and Ravens in the creation of the SkinWalker. And that some other catalyst — like Malvina breaking out the WMDs or Stone backstabbing the Wolves after bringing them to Terra — will catapult the Wolves into the ilClanship and the creation of a “Third Star League”.
But I also suspect that, like the Jihad and WoR storylines, the major strokes of the ilClan story will be unpredictable.
