The primary purpose of the Naval Criminal Investigative Service (NCIS) is to investigate major criminal offenses, particularly those related to the Navy and Marine Corps. This includes a wide range of activities such as investigations into crimes like sexual assault, espionage, fraud, and terrorism. By focusing on serious criminal activity, NCIS plays a crucial role in maintaining the safety and security of naval personnel and assets.

This focus on investigation is essential because it helps to uphold military law and discipline while also ensuring that justice is served in criminal cases affecting naval operations and personnel. The investigative efforts of NCIS are therefore central to the overall mission of protecting the integrity of the Navy and Marine Corps, making it a vital component of military law enforcement.
