I'm looking forward to seeing if any of the Terran militia forces named in IlClan, from places like Nepal or Mongolia - or, indeed, from Japan - are going to be followed up on in IlKhan's Eyes Only. Something which provides more variety to the new SLDF, in terms of the portion of its ranks being drawn from the local population across Terra.

Also, in the longer term, I might wonder if those Clans aligned with the new Star League might phase out the concept of second-line, solahma, and/or PGC forces entirely - with all of those duties being folded into the new SLDF?
Or, to put it another way: I could see the Terran Falcons and Smoke Jaguars not bothering to set up such forces in the first instance. And, in a sense, the Snow Ravens are half-way there, given that they continue to defer much of the protection of the Raven Alliance to the AMC regiments. But, might the Wolves themselves find themselves going in that direction, whether they intend to or not?
And might this mark a break between those Clans which adopt this kind of split on the one hand, and those (such as the Hell's Horses, perhaps) who might retain their current force organization structure?
That said, I could see the Sea Foxes not being in a hurry to invite new SLDF forces to places like the Chaine Cluster, even if they find themselves supporting new SLDF deployments elsewhere in the Inner Sphere and near Periphery...
