The Requiring Activity (RA) has requirement to acquire new parts for the existing Marathon Target Systems (Autonomous Robots) for Live Fire Training. These target are mobile and react the same as a person under combat conditions. These parts will be used during training exercises at Fort Bragg, NC; White Sands Missile Range, NM; and Fort Bliss, TX. These replacement parts will enable the RA to simulate live fire action with currently owned Marathon Target Systems. No services are required for this supply order.
