Jokes aside I do feel that the CapCon honestly lacks certain things that makes it intreasting, intreasting subdivisions and subfactions (hell with the MAC leaving what intreasting REGIMENTS does the capcon have these days?
While its true that the CapCon is pretty much completely monolithic nowdays, making it a bit drab, it's its evolution that makes it interesting. Maybe I'm missing something (I've been left in the dust post-jihad and am simply unable to catch up), but of the major houses, it's definitely the one that has known the greatest changes in policy since 3025.
Back then, while the chancellor ruled supreme, the dynamic of underhanded check and balance ( I mean, "the closest thing to a friend" to Maximilian Liao is a bloody mask agent, you know he's there to off him if need be, this is the bleedin' capcon we're talking about) between the CCAF, warrior houses, the prefectorate, the chancellor, the maskirovka and to a lesser extent the death commandos and the house of scions, it makes for quite the explosive situation. And then everything crumbles and things change dramatically, the chancellor becoming ever more powerfull, imposing a dramatic change in policy making and in the policys themselves from chancellor to chancellor (although we doN,t get all that much detail, some is sketchy and I do seem to recall contradictions in the otherwise very well done 3067 handbook).
As for interesting regiments today, how to bypass the Tau Ceti Lancers?
The Tau Ceti Rangers of old (and the absorbed remnants of the 15th dracon) were quite unique in being "hard-luck, ex-star league, semi-mercs" which kept true to ancient ideals, upheld the spirit of the "unofficial late-SW Ares convention revival" which in a sense also meant sticking with what "the capcon has best to offer" in terms of values, from a korvin doctrine and lorix order kind of way. Those two regiments had a very rich tradition, and the Tau Ceti Lancers are steadfastly keeping it alive in the 32nd century.
Warrior houses still have a little something, of course, but then they don't have all the flavour they used to. Pour House Lu Sann, your dubious loyalty and upholding of higher ideals even against the interests of the celestial wisdom is sorely missed.
Talking about interesting/quirky regiments...are Marshigama's Legionnaires still live and kickin' at the current point in the timeline?
