2d Lt Samuel K. Riehn serves as a contracting officer within the FA4855 27th Security Forces Squadron Logistics, part of the Department of the Air Force, where he supports the sustainment and modernization of critical air base infrastructure. His responsibilities include managing the full lifecycle of procurement actions for facility services, communications systems, and mission-critical support contracts, ensuring alignment with Air Force readiness objectives. He routinely handles complex acquisitions under FAR Part 19 for small business set-asides, coordinating with engineering and operations teams to translate technical requirements into compliant, competitively awarded contracts that enhance base resilience and operational continuity.
