The CryoForge RPU-3 is a man-portable cryogenic unit designed for battlefield medicine -- capable of flash-freezing a wounded combatant's entire body to cryogenic temperatures in under ninety seconds, halting biological degradation and buying time for evacuation to a surgical facility. Unlike Lazarus's CryoVault, which is designed for long-term preservation with careful preparation, the CryoForge is designed for emergency use: minimal prep, maximum speed, acceptable collateral tissue damage. The unit weighs 34 kilograms, deploys from a backpack configuration, and uses expendable cryogenic cartridges that provide enough cooling agent for a single full-body freeze.

Crucible developed the CryoForge for Arcturus combat medics operating in environments where evacuation times exceeded the golden hour for trauma survival. The system's approach is deliberately crude by medical standards -- it floods the subject with an aerosolized cryoprotectant through forced inhalation and dermal absorption while simultaneously cooling the body's surface through direct contact with cryogenic gel packs. The process is painful, traumatic, and saves lives that would otherwise be lost. Revival requires specialized equipment available only at military field hospitals, and the revival process itself carries a 12% complication rate including frostbite damage, cryoprotectant toxicity, and what medics call 'freeze shock' -- a neurological event caused by the brain's reaction to being flash-frozen and revived.

The CryoForge has found an unexpected secondary market in the criminal underworld, where its ability to freeze a person into temporary stasis has applications that Crucible's marketing department prefers not to acknowledge. Kidnapping operations use modified CryoForge units to immobilize targets for transport. Underground fighting rings freeze injured combatants between rounds to keep them fighting. The Shelf's medical cooperatives have adapted the technology for emergency preservation of patients who cannot reach surgical care in time -- a humanitarian application that Crucible has declined to either endorse or prosecute.
