The Military Cooperation with Civilian Law Enforcement Agencies Act is a United States federal law enacted in 1981 that allows the United States Armed Forces to cooperate with domestic and foreign law enforcement agencies. Operations in support of law enforcement include assistance in counterdrug operations, assistance for civil disturbances, special security operations, counter-terrorism, explosive ordnance disposal (EOD), and similar activities. Constitutional and statutory restrictions and corresponding directives and regulations limit the type of support provided in this area. The legislation allows the U.S. military to give law enforcement agencies access to its military bases and its military equipment.{{cite news|last1=Balko|first1=Radley|title=A Decade After 9/11, Police Departments Are Increasingly Militarized|url=http://www.huffingtonpost.com/2011/09/12/police-militarization-9-11-september-11_n_955508.html|accessdate=29 November 2014|agency=Huffington Post|date=11 September 2011}} The legislation was promoted during the Presidency of Ronald Reagan in the context of the War on drugs, and is considered a part of a general trend towards the militarization of police.
