This is the official webpage of the United States Coast Guard Investigative Service. "The Coast Guard Investigative Service (CGIS) is a federal investigative and protective program established to carry out the Coast Guard's internal and external criminal investigations; to assist in providing personal security services; to protect the welfare of Coast Guard people; to aid in preserving the internal integrity of the Coast Guard; and to support Coast Guard missions worldwide. The Coast Guard Investigative Service is a federal law enforcement agency whose law enforcement authority is derived from Title 14 of the United States Code. This authority provides for Coast Guard special agents to conduct investigations of actual, alleged or suspected criminal activity; carry firearms; execute and serve warrants; and make arrests. Today CGIS is comprised of approximately 90 active duty military and civilian special agents and 150 special agents who are members of the Coast Guard Reserve. In a period of declining budgets and personnel resources, CGIS remains firmly committed to providing effective law enforcement services, with minimal financial impact to the taxpayers of the United States."
