Bounty hunters, as the name suggests, are individuals who complete tasks assigned by their employers in return for bounty rewards. However, the employer in this case is not an individual but the government of the survivor bases!
For those New Humans who are unwilling to be recruited, the government will not force them. After all, provoking a New Human could result in greater casualties. Nevertheless, those officials in the government are not fools. They naturally have various ways to exploit these uncooperative New Humans.
Such as by posting bounty missions, providing them with you with work that'll allow you to survive. It is essentially a way of subtly hiring these New Humans as laborers or temporary workers.
