The USSP gets a new piece of tech, the little red book. its researchable around the midpoint of their tech tree and the commissar starts with one in their office. When the book is used by a serzhant or the commissar on a non-mindshielded individual, it converts them into a USSP conscript, it works on humanoid species (players), humanoid mobs (dungeon npc's and clones), and monkeys/kobolds. When used on a non-sentient creature it injects a small amount of cognizine into them.
When a person becomes a USSP conscript, they get a popup telling them they're USSP aligned and that they must follow any millitary orders given to them by USSP officers. In exchange, USSP conscripts can interact with a new kind of console on the USSP stations that gives them 120,000 credits for every hour they've been converted. Conscripts can cryo at any time to de-convert themselves, but they get a popup telling them they dont remember anything that happened while under USSP control. Conscripts also innately understand and can speak the USSP language.
Conscripts are not obligated to follow orders they consider to not be millitary related, such as menial labor or enforced behavior such as remaining in a specific place. Conscripts can also break control at any time by entering and leaving a cryo pod.
Conscript monkeys are no longer clumsy.
Members of other factions (TSF and ASR) are totally immune to conversion, as are medical staff (Responders and the DoC). In the implants tab of the loadout screen is a 1,000 credit mindshield implant, when injected it prevents all conversion and cannot be removed. The ASR and TSF can also research craftable versions of these.
