A sustenance system provides a way for you to consume sustenance without removing your armor or shutting down environmental protections. The basic version of this system holds 1 Bulk of actual food and drink, whether field rations, R2Es, or other cuisine. Higher model numbers function as miniaturized culinary synthesizers of the same model number, allowing the armor to produce food and drink from UPBs on verbal or text command. These non-basic systems can also store up to 1 Bulk of UPBs.
