Which of these is NOT a faction included in the game Counter-Strike: Global Offensive?

The answer is BOPE (Batalhão de Operações Policiais Especiais) because it is not a faction included in the game Counter-Strike: Global Offensive. Counter-Strike: Global Offensive features factions such as the Counter-Terrorist teams, which include the FBI, SAS, GIGN, and SEAL Team 6, as well as various Terrorist factions like the Phoenix Connexion and the Elite Crew. However, BOPE, which is a special police unit in Brazil, is not included as a playable faction in the game.
