ACN/EXBS advances U.S. national and economic security by strengthening recipient country capabilities for export controls, customs enforcement, points of entry (land, sea, air), and border security operations to identify, disrupt, and prosecute state and non-state transnational proliferation activities involving WMDs, their components, delivery systems, sensitive and emerging technologies, and advanced conventional weapons. Coordinate with implementers to ensure timely, compliant delivery of ACN/EXBS activities, guiding strategy, approving materials, and overseeing equipment deliveries (including end-use monitoring, site visits, and impact assessments).
