Step-by-step explanation:
The Federal Air Marshals' (FAMs) duties and responsibilities include safeguarding the security of civil aviation through the deployment of armed federal agents on board select flights to detect, deter, and defeat hostile acts targeting U.S. air carriers, airports, passengers, and crew.
