I try not to Monday morning QB other agencies because Lord knows mine aren't perfect, but the only thing I can really get behind you on is the FF's doing ventilation. The need for vertical ventilation is questionable in my opinion, but since they were up there they obviously needed a roof ladder due to the roof type, and I would've stayed on air. Not sure what you mean by guard on the saw, unless you mean a depth gauge like some departments use on dedicated vent saws. We don't use them. Hard to tell how many FFs are on each engine because the video kept skipping around too much, but I *think* I saw at least 3 come off each unit. If there were only two then that is definitely less than optimal but sometimes it happens in smaller departments. I've done two men and a truck more than I care to admit. The first due Engine could have pulled up a bit more, but the Ladder had plenty of room to operate on a two story house. Water supply didn't look to be an issue, there was plenty of water to put out the fire, and it looks to be bigger than 2.5 in the pics. Just my opinion, obviously yours is different. But I have seen much worse performance by supposedly much better departments.
