Special Investigator

In the United States, a special agent is an official title used to refer to certain investigators or detectives of federal, military, tribal, or state agencies who primarily serve in criminal investigatory positions. Additionally, some special agents operate in criminal intelligence, counterterrorism, or counterintelligence-based roles as well, with one or all of these roles occasionally taking precedence over criminal investigatory tasks.
