In Colombia, the Colombian military is responsible for defending and maintaining the country’s independence, national sovereignty, and territorial integrity but also has a considerable internal security role, which includes protecting the civilian population, as well as private and state-owned assets, and ensuring a secure environment; the military’s primary focus is the conduct of counterinsurgency and counter-narcotics operations against domestic illegal armed groups, including drug traffickers, several factions of the former Revolutionary Armed Forces of Colombia (FARC) terrorist group, and the insurgent/terrorist group National Liberation Army (ELN)

border security is also a focus, particularly with Venezuela where economic and political instability has brought refugees and attracted narcotics trafficking and other cross-border crime; both the ELN and FARC dissidents operate openly in the border region; ELN and FARC insurgents have also used neighboring Ecuador to rest, resupply, and shelter

Colombia has close security ties with the US, including joint training, military assistance, and designation in 2022 as a Major Non-NATO Ally, which provides foreign partners with certain benefits in the areas of defense, trade, and security cooperation; it also has close security ties with regional neighbors, such as Argentina, Brazil, Chile, and Peru; Colombian military and security forces have training programs with their counterparts from a variety of countries, mostly those from Mexico, Central America, and the Caribbean (2025)
