Members of the Brazilian Marine Corps Special Operations Battalion practice maneuvering in an urban environment during a Joint Combined Exchange Training exercise. The course was facilitated by the U.S. Navy's amphibious assault expert SEALS, as well as the maritime mobility experts known as Special Warfare Combatant-craft Crewmen. This bi-lateral training was the first time the U.S. had engaged with this unit in more than 25 years, and strengthens ties between the two nations.
