Doesn't surprise me in the least. Containers of equipment get shipped out, the logistics then have tons of tighly packed equipment to sort out most of which can't be identified and passed onto the end user so just gets stockpiled then lost.
I remember years ago a young soldier at Bremerhaven docks counting landrovers and trailer being loaded on a ship. What she wasn't taking account of was the fact that the land rovers were dropping off the trailers and driving back out to pick up another.
Or the oil pressuge guage put in a box and shipped out to Iraq in the same container as all the ration packs. Needless to say it never reached us.
