In Guatemala, the military is responsible for maintaining sovereignty, territorial integrity, and the honor of Guatemala, but has long focused on internal security; since the 2000s, the Guatemalan Government has used the military extensively to support the National Civil Police in internal security operations (as permitted by the constitution) to combat organized crime, gang violence, and narco-trafficking; in recent years, however, the military has moved to refocus on border security and preparing for conventional operations; it participates in UN missions on a small scale and has a peacekeeping operations training command that offers training to regional countries; the military has security ties with regional partners such as Brazil, Colombia, El Salvador, and Honduras; cooperation with El Salvador and Honduras has included a combined police-military anti-gang task force to patrol border areas; it also has ties with the US, including joint training exercises and material assistance

the military held power during most of Guatemala’s 36-year civil war (1960-1996) and conducted a campaign of widespread violence and repression, particularly against the country’s majority indigenous population; more than 200,000 people were estimated to have been killed or disappeared during the conflict (2024)
