The Municipal Guard is often not used in mostly cities and remain as spare forces of the Military Police. They hold no weapons and respond to minor criminal activities, and with similar rank titles as the Federal Police. Brazil also counts on the "Polícia Científica" or Scientific Police. They are responsible for the investigation of scenario, evidences, etc. Since they job is to do the forensic aspects of criminal actions, they do not perform investigative work like the Civil Police, who share similar rank titles.
