Which unit is primarily involved in national security advisory roles?

The National Security Advisory Unit is primarily involved in national security advisory roles due to its focus on providing strategic guidance and recommendations related to national security policies and issues. This unit typically works closely with government officials and agencies to assess threats, develop response strategies, and ensure that national security measures are effectively implemented.

Other options may refer to organizations or units that operate in related but distinct capacities or focus areas. For instance, the National Security Bureau and the National Security Coordination Office might handle broader tasks related to security management and coordination among various entities, while the National Screening Unit is likely concerned with the processes of evaluating and screening individuals, which is not directly aligned with providing advisory roles. Thus, the National Security Advisory Unit stands out as the entity specifically designed to focus on advising on national security matters.
