"Being a Tech Savvy is all the rage in warfare. And half-human cyborgs are all rage too!"
Cyborgs are the last resource in the Military industry. Despite unlocking after Air Rescues, the bullet price of cyborgs is nowhere near as difficult as air rescues. In fact, cyborgs are only about 25% more difficult than Laser Drills, though unlocking Cyborgs requires a trillion more comrades. Despite this, ranks that include cyborgs do not go into the billions, nor do bullet missions at this point get to post-inflation era levels nor even exceed Trade 60 Military, making the military industry easy just like land and ore.
