Remains of a Shaheh-123 unmanned aerial vehicle are part of a display at Joint Base Anacostia-Bolling in Washington, D.C. The Defense Department established the Iranian Materiel Display in December 2017 to present evidence that Iran is arming dangerous groups with advanced weapons, spreading instability and conflict in the region. The display contains materiel associated with Iranian proliferation into Yemen, Afghanistan and Bahrain. DOD photo by Lisa Ferdinando
