U.S. Air Force Senior Airman Pak Koo, 7th Logistic Readiness Squadron fire truck and refueling maintenance journeyman, removes a nut from an airbrake system component July 30, 2015, at Dyess Air Force Base, Texas. The FARM shop was able to help the View Volunteer Fire Department through the Public-Private, Public-Public Initiative, or P4 for short, which is an accumulation of projects organized between parts of the local community and base with benefits for both sides.
