Which organization is referred to by the acronym CNIC?

The organization represented by the acronym CNIC is Commander Navy Installations Command. This command is responsible for the management, operation, and oversight of Navy installations worldwide, providing support and services to ensure that their functions are aligned with the Navy's mission and operational goals.

CNIC plays a crucial role in enhancing the quality of life for sailors and their families by providing facilities, housing, community services, and aligning those services with broader naval operations. It also works on the efficient allocation of resources and infrastructure to support naval readiness.

The other options, while related to military functions, do not accurately reflect the specific duties and responsibilities associated with CNIC. The Coastal Riverine Force focuses on coastal operations, the Duty Brig Supervisor deals with specific operational assignments, and the Department of Defense encompasses a much broader range of military and defense-related activities across all branches, not specifically tied to installations.
