C.T.D.
Translation: N/A
Country of Origin: Brazil
Formed: 1983
Parent Organization: 1st Special Forces Battalion
Background:
Brazil's involvement in Counter-terrorism operations dates back to 1953, when a special intervention squad was formed by the Ministry of Aviation. The first dedicated CT unit did not come along until 1983, however, when the Counter-Terrorist Detachment of the 1st Special Forces Battalion was formed.The CT detachment is similar to the U.S.'s Delta Force.
Only those paratroop or special forces soldiers with an exemplary record are
allowed to volenteer--and not many of those will be chosen. According to some
reports, the attrition rate in the 14 day selection phase may be as high as 90%.
Those that are selected undergo a thirteen 
week
training session at a camp near Rio De Janeiro. . The usual items for CT groups
such as marksmanship, combat shooting, parachuting, heliborne insertion, and
fast-roping are all covered, but because Brazil has a varied terrain, special
emphasisis placed on long range patrols and intelligence gathering in varied
environments.
Besides the HK MP-5 and Colt 1911 .45, the members of the CT detachment are profficient at using machete's and dagger. Shotguns include the Remington M870 and the indigenously produced ENARM Pentagun. The favored sniping rifle is the HK PSG-1.
