Our local State emergency services mate.

Mostly volunteers, responding to all types of emergencies like weather, storms, floods, fires. They work in hand with the fire fighters and the cops quiet a lot.
I work on the power grid and get to work with them all the time , mostly during storm, trees down bringing lines down or vice versa.
Some of the shit they do and put up with as VOLUNTEERS on their own time is staggering. Bow to them any moment personally !!!
