Noronha has spent the majority of his military career as a CT operator. He is well-known in the CT community, particularly in North and South America, and has a reputation as a stern taskmaster. Although he has conducted actions in a wide variety of terrains and circumstances, he is particularly proficient in jungle operations and long-range intelligence gathering. In combat situations he is extremely aggressive and he expects the same from any team that serves under him. He has no sense of humor and considers it unprofessional in others. His only passion in life (aside from his work and his family) is classical music and opera.
