From the small island of Mocanguê, in the Rio de Jainero bay, the Brazilian Navy Combat Divers Group can strike anywhere. Whether in the huge Amazon river and its surrounding hostile jungle, or in the oceanic strip of the Brazilian coast, they are ready for any maritime interdiction actions, hostage rescues or facility recovery situations that may arise. They are the tip of the spear of the Brazilian Navy and will play a central security role during the soccer world cup in June and then of the Olympics games in 2016.
