The United States Army Criminal Investigation Command (USACIDC, usually abbreviated as just CID) investigates felony crimes and serious violations of military law within the United States Army. The command is a separate military investigative force with investigative autonomy; CID special agents report through the CID chain of command to the USACIDC Commanding General, who reports directly to the Chief of Staff of the Army and the Secretary of the Army. By position, the USACIDC commanding general is also the Army's Provost Marshal General. (Source: Wikipedia)

The United States Coast Guard (USCG) is a branch of the United States Armed Forces and one of the country's seven uniformed services. The Coast Guard is a maritime, military, multi-mission service unique among the U.S. military branches for having a maritime law enforcement mission (with jurisdiction in both domestic and international waters) and a federal regulatory agency mission as part of its mission set.

The Coast Guard Investigative Service is a centralized directorship managed by a professional criminal investigator who reports to the Vice Commandant of the Coast Guard. The CGIS is located outside the Coast Guard's operational chain of command. This allows consistency in investigative policy, procedure, training and education, in full compliance with the President's Council on Integrity and Efficiency report. All CGIS agents must possess a security clearance and attend courses at the Federal Law Enforcement Training Center (FLETC) in Glynco, GA.
