Yeah.
You ever see one of those pictures from the middle east, the beaten-up old 1 ton truck with the giant AA gun on the back? "Technical - a light, improvised fighting vehicle."
How about a police helicopter? Auxiliary.
According to my notes and headcanon, the Civil Government was adding suspicious pieces to civilian vehicles - nothing really noticeable, just things like supports slightly stronger than they had to be, oversized fuel cells in multiple vehicles as a 'cost saving measure', busses that used noticeably better suspension than previous models. That kind of thing. Then, when those vehicles were spotted with Pintle mounts and a couple hundred kilos of Bar-6 armor, the cars were parted out for military spares on trailers, etc., and the old tires and seating on the busses switched out with All-Terran wheels and mounting Satellite Uplinks with drone control stations, it suddenly made a lot more sense.
