Colombian Army
The National Army of Colombia (Spanish: Ejército Nacional de Colombia) is the land military force of Colombia and the largest and oldest service branch of the Military Forces of Colombia. It is responsible for carrying out land-based military operations along with the Colombian Naval Infantry (Infanteria de Marina) and for protecting the Colombian state against domestic or foreign threats.
The modern Colombian Army has its roots in the Army of the Commoners (Ejército de los Comuneros), which was formed on August 7th, 1819 – before the establishment of the present day Colombia – to meet the demands of the Revolutionary War against the Spanish Empire. After their triumph against the Spanish, the Congress of Angostura created the Greater Colombian Army, to replace the disbanded Commoners Army.
