Probably, but we also have to note they've at least got drones and some kind of first-class Electronic Warfare kit, we don't know that they don't have some other horrible trick up their sleeve that could reverse the situation.
Like I said, an immediate matchup isn't remotely
favorable, just we've reached the point where we can at least not be straight curbstomped if they come at us.
I kinda feel between us, the Pirates with WarShips, and the Romans who've managed to build power armor, that we're looking at a reversal of the typical BT map. That is to say the Inner Sphere great houses are a bunch of primitives and the periphery nations are packing serious technology. It's a common fanfic trope but I'm wondering if this isn't a situation where several such super-advanced periphery nations are active all at once rather than a single outlier.
It's a completely realistic take, to be honest.
The Inner Sphere is the classic bucket of crabs where no one can ever move forward because the others will pull them down. The "established" Periphery is somewhat less affected by this (as the Periphery powers are generally saner than the Great Houses), but they're still within the reach of the nastiest crab (ComStar, of course) and also started out way behind due to the Star League both actively and passively fucking them over.
The benefits of simply
exiting the crab bucket are dramatically demonstrated by the Clans, who are
even stupider than the Great Houses and have almost completely self-sabotaged themselves into a society and culture that makes the
Soviet Union look healthy by comparison. And yet
even with that self-sabotage, they have been able to easily leap substantially ahead technologically simply because they added kiddie gloves (zellbringen rules) to the shiny new crab bucket they built for themselves.
We are in neither crab bucket, and so are all the other isolated far Periphery powers. Those that had more access to original Star League tech have a significant leg up, but the lack of crab bucket sabotage means that every remotely stable surviving power in the Periphery can be expected to, over time, become
at least as advanced as the Clans.
