Other features on this Striker ARFF include:
  • Forward-looking infrared (FLIR) thermal imaging camera for identifying hot spots in and around the aircraft
  • Dual #Scania DC16 V8 Tier 4F engines
  •  #TAK4 Independent Suspension for unmatched stability and maneuverability
  • 360-degree camera for enhanced awareness and visibility all around the truck
