Bears repeating.
1600M you would think means 1600 million, which is 1.6 billion.
However:
Page 29 of the Defense Logistics Agency, Customer Assistance Handbook lists the QUP (Quantity Unit Pack) as M=50.
The purchase order for 1600M equals 1600 boxes of 50 rounds.
I’ve only been using the national stock system for 42 years so what do I know.
