The Operational Test Command (OTC) is a U.S. Army organization responsible for conducting operational tests of new Army, Joint, and Multi-Service systems to ensure their effectiveness, suitability, and interoperability under realistic conditions before they are fielded to the Army. Headquartered at Aberdeen Proving Ground in Maryland, OTC consists of three test units: the U.S. Army Aberdeen Test Center, U.S. Army Yuma Proving Ground, and Dugway Proving Ground. These testing facilities offer various terrain types, climatic conditions, and military infrastructure to support rigorous and realistic tests. The Operational Test Command plays a crucial role in maintaining the readiness of the U.S. Army by providing reliable and objective data about new systems to inform decision-making processes related to their acquisition and deployment.
