U.S. Army Operational Test Command (OTC)
Operational test command · Evidence strength: CONTEXTUAL
OTC conducts independent operational testing that helps determine whether Army systems are effective, suitable, and survivable in realistic operational conditions.
OTC is an ATEC subordinate command and operational testing component.
Location: Fort Cavazos, Texas, formerly Fort Hood.
Components: Operational test directorates, Airborne and Special Operations Test Directorate, Air Defense Artillery Test Directorate, Fires Support Test Directorate, Intelligence Electronic Warfare Test Directorate, Aviation Test Directorate, Maneuver Test Directorate, Mission Command Test Directorate, Maneuver Support and Sustainment Test Directorate, Soldier and unit test events, Air defense and fires test contexts, Maneuver and mission command operational testing
Operational tests influence acquisition confidence, fielding decisions, sustainment planning, and contracting support requirements.
OTC connects equipment, soldiers, doctrine, threat-representative scenarios, and test evidence.
The connection is contextual unless a specific Joel role document names OTC; ATEC biography evidence supports broader command environment relevance.
