Thinking about creating an opfor for my players in a future campaign got me wondering which commands are what would be considered the workhorses of each Successor State. I'm talking here of commands that are not the elite, but solid units that are most of the time the one their States would field for combat operations, knowing those are dependable units.
The question here is what your calling "Elite".
Like, do you mean the "Royal Guard" type unit, or do you mean the "Skill" level, since frankly, those are not the same thing.
So if I'm trying to come up with a "ranking" for your Workhorse, it's important to look at that Name Recognition but also Skill Level, & "Supply Rating" and even "Regional Area" since for some factions you can really have a diverse "Regional" force.
The Robinson Rangers =/= Draconis March Militia.
While Pesht Regulars =/= Donegal Guards.
For the FedSuns I think you hit the nail on the head. The Hussars/Lancers are top end units but also not died to a region, they aren't the "Royal Brigade" either.
For the DC I think it's really hard. Dieron Regulars "might" qualify as the "best" of the Regs, but also the Ryuken depending on the era. Proserpina Hussars is a smaller organization but I think they could qualify as being Workhorse for being really good but also not he SoL brigade.
For the LC, I really feel the Lyran Guards as well as the Donegal/Arcturan units are where your looking here.
Generally they are top tier in terms of supply/skill but also are not the Royals & aren't really "Regional" the way Skye units & some of the newer brigades are w/ 1 unit per region & overall are defensive.
The CC is honestly the hardest to pick from BUT, if I had to, I'd probably call it the Warrior Houses as a whole.
They are well funded & usually quite skilled and are not tied to a region as "Defenders/Reserves".
That is really the thing w/ the CC, they have boatloads of Regional units like the DC does but none of them is quite your "Offensive" unit or "Workhorse".
So with that in mind, I gotta stick w/ the Warrior Houses, good over all, very from Elite to Regs & change w/ era, but, not regional, & also not Death Commandos, MAC/Mercs, or CapHussars brigade.
