Nanoreagent hydrocarbot

Nanoreagent hydrocarbots are a suspension of nanomachines that render nearly all carbon-heavy matter into usable fuel for the UNSC's ubiquitous internal combustion power plants, including he hydrogen-injected internal combustion engines used by the M12 Force Application Vehicle and the M274 Ultra-Light All-Terrain Vehicle. UNSC personnel colloquially refer to the nanomachines as "slop".
