A few years ago there was a blog site out of Fairfax County that was a good source of material if you were looking for something to train about or discuss with the others on your shift. Unfortunately it died away, but it has now come back with new content and a new look.
Formerly known as the Battalion 5a blogspot, FireTactics.net has resurfaced with good, short and concise information to make you think. Ron Kuley and Keith Bresnahan manage the content which most recently calls you to remember all the sides of the fire building.
Especially the rear.
