Had me there for a moment, haven't thought about it as the Manual of Air Force Law (MAFL) for 40 years (when I thought of it at all). It is probably equivalent to the Uniform Code of Military Justice (If I guess right).
It was full of case law and study and an essential part of our promotion system. The early edition was hard bound, as in keeping with legal documents but kept updated with amendments such as "insert the following 3 paragraphs between esential and part above." It was full of marginal notes, stick in notes, extra tabs, pencil cribs etc from countless unknown officers in the past all seeking promtion to flt lt.
Now it is a pristine loose leaf book, same size and format as QRs (which is Queens Regulations (Air Force) and rarely read at all and usually only by the legal eagles.
