Dense Urban & Subterranean Cell (DUSC)
The Dense Urban & Subterranean Cell (DUSC) is a cadre of current and veteran urban security practitioners who have demonstrably committed their lives and their careers to confronting the complex challenges of the dense urban environment and facilitating the health and well-being of those that reside within. Members are diligently selected for this role by NCUO leadership based on their experience and performance. Each plays a continuing role supporting conceptual, educational, training, and material solution development. Inclusion in the below list does imply professional endorsement of the NCUO mission and orgaization but does not imply financial or contractual relationships. NCUO reserves the right to revoke inclusion at the discretion of leadership. The DUSC crest reflects the iconography of the US Army’s now-deactivated Asymmetric Warfare Group, an organization whose mission, men, and contributions are already missed by the Joint Force.
