Which military group in Nicaragua did the CIA support during the Reagan administration?

During the Reagan administration, the CIA provided significant support to the Nicaraguan Contras, a group that opposed the Sandinista government. The Contras were made up of former members of the Nicaraguan National Guard and other anti-Sandinista factions. They received funding, training, and logistical support from the United States as part of a broader effort to combat leftist movements in Central America during the Cold War, particularly those aligned with communism.

The U.S. government's policy aimed to undermine the Sandinistas, who had taken power after the 1979 revolution and were seen as a threat to American interests in the region. The support of the Contras was controversial, leading to debates over U.S. foreign policy and the ethical implications of military engagement in foreign conflicts. The funding and aid to the Contras were made possible often through covert operations, highlighting the complexities of U.S. involvement in Central America during that period.
