The White House Strategy to Combat Transnational Organized Crime of July 2011 is organized around a single, unifying principle: to build, balance, and integrate the tools of American power to combat TOC and related threats to our national security – and to urge our partners to do the same.  Learn more about CTOC Strategy

U.S. Central America Regional Security Initiative (CARSI)

The desired objective of CARSI is to produce a safer and more secure region where criminal organizations no longer wield the power to destabilize governments or threaten national and regional security and public safety, as well as to prevent the entry and spread of illicit drugs, violence, and transnational threats to countries throughout the region and to the United States.  Learn more about CARSI

Joint Interagency Task Force South (JIATF South)

The Key West, Fla.-based JIATF South is the National Task Force that serves as the catalyst for integrated and synchronized interagency counter-illicit trafficking operations, and is responsible for the detection and monitoring of suspect air and maritime drug activity in the Caribbean Sea, Gulf of Mexico, and the eastern Pacific. JIATF South also collects, processes, and disseminates counter drug information for interagency and partner nation operations.  Learn more about Joint Interagency Task Force South

Department of Defense role

While the Department of Defense is not the lead agency responsible for countering TOC networks, its unique capabilities can be leveraged to support other U.S. government and partner nation efforts.  SOUTHCOM is aligned with and supports lead agencies, such as the Departments of Justice and State, as well as partner nations in the C-TOC fight.  Learn more about DoD/SOUTHCOM CTOC efforts

Department of Defense interdiction role explained

The DoD is the lead federal agency in efforts to detect and monitor aerial and maritime transit of illegal drugs towards the United States.  Based on information gathered by JIATF South-coordinated operations, U.S. law enforcement agencies and partner nations take the lead in interdicting drug runners.  U.S. military interdiction involvement, if any, is in support of those law enforcement agencies. 

Typically, U.S. military personnel are involved in supporting an interdiction during maritime operations in international waters, where U.S. Navy ships and helicopters patrol and intercept suspected traffickers.  The actual interdictions – boarding, search, seizures and arrests – are led and conducted by embarked U.S. Coast Guard Law Enforcement Detachments or partner nation drug law enforcement agencies.
