COMANF

The Marine Corps Special Operations Battalion, also known as Tonelero Battalion or Amphibious Commandos (COMANF), is a special operations battalion of the Brazilian Marine Corps. Its attributes include planning, conducting and executing special reconnaissance, direct action, counterterrorism and hostage rescue operations in support of Brazilian Marine Corps operations.

History
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.

Despite initially being a reserve battalion for the Marine Corps, by 1996 COMANF had welcomed an Amphibious Recon Company and a Land Recon Company into its ranks, having become the Marine Corps' main unit for special operations and becoming directly subordinate to the Marine Corps Command.
