(U.S. Marine Corps photo) The Marines successfully completed a Tactical Resupply Unmanned Aircraft System (TRUAS) Field User Capability Assessment (FUCA) in March at Yuma Proving Ground, Arizona, of two prototype systems identified by a successful prize challenge in last year. Anticipated future end users were given the opportunity to work with both prototype systems – Survice Engineering’s TRV-150 and Chartis Federal’s MK4-RX – to assess the capability in order to inform the final requirement for TRUAS.
