In 2384, aboard the USS Dauntless, firefighting was a section in Security, and the firefighters were assigned to squadrons. That year, four firefighters from Squadron 5 were working in concert with the fire fighting system to extinguish a fire in the shuttlebay. The fire had started in the starboard warp nacelle of a Type 9 shuttlecraft. This situation was being monitored from an operations console on the bridge. (PRO: "Mindwalk")
