U.S. Special Operations Forces operate a fleet of portable, rapidly deployable field workshops that can repair, manufacture, or even improve equipment in the field. The workshops, known as Mobile Technology Repair Complexes, are powered by renewable energy and stuffed with tools including lathes, welders, and 3D printers. MTRCs have proven their worth in the war against the Islamic State in Syria, quickly building ad hoc medical facilities from available materials.
According to DefenseOne, U.S. Special Operations Command (SOCOM) has thirteen MTRCs worldwide. The complexes are designed to be portable and capable of rapidly moving into war zones, supporting special forces working in dangerous areas with a minimum of support. The complexes are modular, with individual modules based on eight foot shipping containers that expand, tent-like, to a length of twenty four feet. Each module can be carried by a five ton truck or slung underneath a CH-47 Chinook transport.
