What resources are used when firefighters are fire fighting?

A fireman's greatest resource, of course, is water and the #1 place they connect with that is fire hydrants (why not water hydrants?). Also at the fireman's disposal are trucks with compartments for tools, hoses, the Jaws of Life, breathing apparatuses, extra suits, axes, picks and a growing number of tech devices. Oh yeah, let's not forget those ladders for reaching those stranded at heights!
