Teams will patrol the Washington Metro system, as well and will consist of two air marshals, one TSA bomb-sniffing-canine team, one or two transportation security inspectors, one local law enforcement officer, and one other TSA employee.

Some members of the team will be obvious to the traveling public and wear jackets bearing the TSA name on the back. Others will be plainclothes air marshals scanning the crowds for suspicious individuals.
It is unclear how many Viper teams will be on patrol through the New Year's holiday, but air marshal officials confirm that they will be at seven locations across the country.
