I am currently taking the online course and am 3/4 of the way through. The Brunacini's have a good training and I believe the system is good. Without knowing about the blue card way of doing command our department already does the basics of the system.
We are an all volunteer dept. and I believe I'll take some of the things they teach to use but it doesn't really fit our dept. to use everything, ie. engine, truck, rescue companies. I believe command boils down to someone who knows how fire acts and having a strong presence on the scene to be able to mitigate the scene safely and effectively.
We do not use the blue card system. There is a smaller paid department near us that uses. From what I can gather through speaking with the firemen on that dept. and hearing the radio traffic during incidents they have had. The Blue card system of command, has alot of radio traffic. It also seems geared more for a small dept. with few fires. Sort of a micro manage the inexperienced crew type thing.
In my opinion it is a bit silly.
By the way Roger, I love your work, THE WALL is a Rock masterpiece.
