In post 21, the conversation I was referencing was casual in nature. In fact, I believe they just said "trucks" or "engines" when speaking about the need for a channel to put them on. When I spoke of the surge crew order of additional trucks/engines, that was based off of a social media post and not heard through a radio transmission. The surges included different types of structure and wildland engines based on social media pictures I've seen. "Surge" is a term used by the various incident management teams on the fire in their official video updates. I assume the surge crews were for additional structure protection, line creation, burnouts etc.
Interesting that various incident management teams have used the term "surge." The last time I heard it used in an official capacity was during the Bush Administration to describe a huge and sudden increase in troop numbers in Iraq. It was a term used for political purposes.
The dictionary of wildland fire terminology is complied by the National Wildfire Coordinating Group. It defines "surge" as a "rapid increase in water flow which may result in a corresponding pressure rise." Hydraulic principles are very important in wildland firefighting. When my late Hubby was on a volunteer fire department and wishing to increase his qualifications and usefulness, studying engine hydraulics was important, but fairly easy for him, given his education/experience as a civil engineer. I'm sorry to see that an agency has adopted a term that seems to be rooted in the media and social media, both of which possess very little understanding of fire management.
What is a better way of describing a sudden increase in resources on an incident? I would just relate how many additional engines, dozers, crews, overhead, aircraft had been ordered and their expected first working shift. That is how it is done, at least on InciWeb and other good sources available. I've not heard anyone in the fire profession use the word "truck" and "engine" to refer to the same apparatus. For obvious reasons the differences are important.
