A brief overview of the Neo-Soviets.

They're built from four basic colony-states-each with a differing culture.

You've got the so-called core colonies-the ones that went all in on communism, and built their entire identity around it. These poor SOBs had the misfortune to be the first ruled by the pain-slave using aristocrats and their AI friend.

Then you've got what I'll be calling the Hivers-cybernetic colonists, adopting themselves to a harsh, arctic environment. Based out of massive, sprawling cities built around geothermal vents-or "human hives" if you will. 

Then you have the Confederates-a loose group of miners, and rough and tumble types settled on a string of questionably habitable, resource-rich worlds. These guys love their hardsuits.

Finally, you've got the genetically engineered super soldiers I mentioned, originally a US marine unit, co-opted and brutally modified by the AI, these guys look human, but they're a shit ton deadlier and their genetic code could, charitably, be called "fucked".

The CentralGov has to make all of these groups get along like good communists.

The Premier could also be called "chief cat herder".
