MilTech_Prosthetic was a peripheral limb replacement developed by MilTech Corp in 2344 as a contractual project for the CSUEAA army to combat trigger-pull-hesitancy. It was co-developed in secrecy with the OpenBladeAI project, but never reached full production.

After MATA corporation acquired MilTech in 2374, the prosthetic was repurposed to equip the mass-produced semi-sentient AI MATABOTs and eventually sold to the public as MATAARM - " the arm of the cyber-citizen", (in)famous for its independent decision making and constant information flow to MATA servers.
