In Army garb and the Pacific Northwest, the new CST vehicles are white, instead of dark blue, when the Air Force/Air National Guard were doing the work. This is the entire fleet, Suburban, armored chemical weapons detection rig (has the mass spectrometer in it), and pickup truck support fleet.
Looks like some upgrades are in progress.
I also find it interesting that WHCA still uses the term "Roadrunner" Rigs when the ones shown do not have the huge VHF antennas on the rear corners, that made for that term "Roadrunner" like the bird and its tail feathers.
