Reminds me of back during the Viet Nam War, the Philippines was a huge logistics hub, and ships would offload supplies, that were then trucked to the airbase and flown by C-5 and C-141 and C-130 transports (and commercial for some) to various points in Southeast Asia.
To support the local economy, the trucking was contracted to local drivers, and pilferage was a real problem, until - someone got the bright idea to open the back of the trailer once loaded, snap a Polaroid photo (along with the smiling driver), then with a permanent marker, number all the exposed boxes, and the photo was sent ahead to the receiving shop at the air base.
Pilferage all but ended.
