You both make good points, though I think the use of "civil" to mean "governmental" is a bit specific for this sort of general guide. I haven't read the book, and don't know if the examples are government vehicles or commercial ones.
The cover sheet and preview pages show what looks to be an Eastern European Dept of Transportation type truck. The numbering of the roller seems like a very governmental way of tracking things. Maybe Carlos can enlighten us on the equipment. I will probably get the book at some point.
