Rapid Mandatory Volunteer Protocol (RMVP)

The Brasch recordings take 9 minutes to walk a Helldiver through training and then you need to transport them from whatever planet they are local to -> mars -> super destroyer which can wind up taking up to 9 hours for a super destroyer to replenish its reinforcements.
This method takes 11 minutes start to finish with multiple mandated volunteers being strapped naked, tubes shoved in their holes, encased in 3D printed nano-latex gear, and hypnotized/programmed. In 33 minutes, because they are in a single production line, a super destroyer can simply mosey on to any Super Earth settlement and have a full reinforcement of horny, squeaky Helldivers
