How do you read a Foreign Military Sales case identifier?
A is the six-digit string that appears on every page of a : a two-letter country code for the purchaser, a one-letter code for the that prepared the case — B for the Army, P for the Navy, D for the Air Force — and a three-letter case designator that agency assigns, whose first letter usually signals the category of what is being sold.

The case designator

The should be used on all documentation relating to the case, including amendments and modifications, as well as logistical and financial transactions.
