Used often in the criminal justice context, a "task force" is a unit that is specially organized for a task. It's also used to refer to special units in the military or government that are dedicated to a specific cause. Ex: To solve the serial murders, the police department organized a special task force. Ex: The Drug Crimes Task Force is dedicated to reducing drug crimes in the city.
