NCIS stands for "Navy Corps Investigative Service"

The statement is false because NCIS actually stands for Naval Criminal Investigative Service, not Navy Corps Investigative Service. The goal of NCIS is to investigate and solve crimes involving the U.S. Navy and Marine Corps, as well as provide security and counterintelligence services to these forces. It is a civilian law enforcement agency within the Department of the Navy, supporting the military by conducting criminal investigations, preventing and countering threats, and promoting the safety and readiness of naval personnel and assets.
