“You give the West way too much credit for competent accounting. Apparently, you’ve never heard of “artillery math”.”
Having worked Military Logistics in a past life, I can tell you that the big concern is TERRORISM, and we, obviously, do not want any large weapons getting into enemy hands, and that concern predated the break-up of the Soviet Union by many years. There is NO WAY that 155s can make it into the Czech Republic WITHOUT our brass knowing it.
You clearly have more faith in the competency of “our brass” than I do.
