1º Batalhão de Forças Especiais (1st Special Forces Battalion) is one of two counter-terrorism(CT) units in the Brazilian Armed Forces (the other being Projeto Talon). The Battalion's mission is similar to that of the US Ranger units; however, because they have the CT mission, they have modified their organization to more closely follow Britain's Special Air Service and American's Delta Force. The SF Battalion falls within the Army's Special Operations Brigade and is located in Goiânia, state of Goiás. The Battalion was given its counter-terrorism mission in the mid-1980s, following expansion to create the 1st SF Battalion. Unit strength is approximately 200 men, divided into platoons. The battalion is capable of conducting its missions independently from or in conjunction with conventional forces. Battalion troops are trained in jungle warfare at the Army's CIGS jungle warfare school and in amphibious, mountain warfare, airborne, airmobile and HAHO/HALO operations. They are also prepared for long-range reconnaissance in addition to their CT operations.
