McChord Reserve cops drive through ATV training Published July 18, 2013 MCCHORD FIELD, Wash. -- One of the main vehicles a security forces Airman might need when they're deployed in the field is an all-terrain vehicle. For that reason, and because 446th SFS Reservists are deployable, they are required to take the ATV course every two to three years. Some 446th SFS Airmen have utilized those skills here at McChord Field to provide support for other security personnel, and incident response during major events, including air shows and Air Mobility Command Rodeo.
