The Federal Air Marshal Service and Transportation Security Officer roles both serve security functions within the transportation industry. While the Air Marshal is a law enforcement officer focusing on onboard security and covert operations, the TSA officer primarily conducts passenger screening at airports. Both positions require security training, but the Air Marshal role involves firearms and law enforcement credentials, making it more specialized and enforcement-oriented.
