There have been several trucks almost identical (except for color) to your photo in our area (western NC) this week. They are with the fire fighting trucks that have been brought into the area to deal with forest fires. I am not sure how many different agencies are in the area, but the Southern Area Type 1 Incident Management Red Team and The Southern Area Blue Team are providing all the status updates.
It has been a busy week - we are about 2 miles from the local airport.
Incident Resources:
23 crews, 6 helicopters, 72 engines, 14 dozers, 3 water tenders, and 1,049 total personnel
