What is the role of SDDC?

• A. DOD executive agent for public highway matters; coordinates highway policy between military and civilian authorities; resolves permit denial
• B. Oversees unit armory operations
• C. Handles military vacation scheduling
• D. Manages recruitment

Answer: (A)

SDDC is the DoD executive agent responsible for surface transportation matters, especially highway issues that affect military mobility. This means it coordinates highway policy between military and civilian authorities, ensuring DoD needs align with state and local road rules, permits, and access. When a permit for movement on public highways is denied or requires coordination, SDDC leads the effort to resolve it and secure the necessary approvals. This role directly supports the safe, legal, and efficient movement of equipment and personnel by road. Functions like armory operations, vacation scheduling, or recruitment aren’t part of this role.
