Charlie's gone through several training classes and in this picture he's participating "MVC" (Motor Vehicle Crash) training. Learning how to use the Jaws of Life, how to cut the windshield out of a vehicle, how to break windows to get access to passengers trapped in the vehicle and so on. The instructor allowed me to be there to photograph the training.
I actually learned a lot while observing and taking pictures. Even though it was only a training session at the firehouse when anyone was using any equipment all joking was put aside and they were focused on the task at hand with the mindset that someone was in the vehicle needing rescuing.
