I had a cousin that worked private security, and for a few years (I think it was early 2000's) his main gig was to work as a team of armed security, and follow trucks from the two Intel campuses in Oregon to the airport in unmarked vehicles, get on the cargo plane with the cargo, and fly to the location where they did the packaging of the wafers (I want to say it was the Philippine Islands) and then fly back. Lots of overtime.
