This message is from Kyle Bernaciak: Engine 103 was included in this drill because, if either Engine 26 or Truck 7 is unavailable, they are the next unit on call to operate the 6-3-1. I was told that Battalion 4 also plans to conduct similar drills with other companies in their area to ensure everyone is comfortable and familiar with the equipment. The 6-3-1 is an incredibly valuable tool, especially in situations where fires need to be "smothered" — like in basements, confined spaces, or small storefronts. It helps firefighters contain and suppress fires quickly and effectively, which can make all the difference in saving lives and property. It's always great to see these units in action and to understand their role in emergency response. Thanks for sharing the photos, Kyle — they're a great reminder of the importance of preparedness and teamwork in the fire service.

These images really capture the unit in action, showing how it operates under real conditions. The drill involved Engine 26, Truck 7, and Engine 103, and was supervised by Battalion 4.
