==History== thumb|270px|COMANFs train in the Cerrado during Operation Formosa 2016 The Tonelero Battalion (named after the Passage of the Tonelero) was created in the 9th of September 1971, due to the Marine Corps' interest in having a unit dedicated to anti-guerrilla warfare. At first, the battalion had a Command and Service Company and a Special Operations Company, which was structured similarly to one of the Marine Corps' infantry companies. In 1972, the first class of officers passed the battalion's selection, then called the "Counter-Guerrilla Course". Tonelero selection would then go through several changes throughout the years before being named "Special Course of Amphibious Commandos" (CEsComAnf) in 1998.
