You learn something every day! One of my readers, sacwriter_1, was a post-Vietnam-Era MP and the MOS for MPs back then was 95B. Nowadays it is 31B. When did it change? It turns out to be in the same time frame as the 'Twenty Years Ago' that Marty and Jake enlisted. That would be 2000, and the change occurred in in 2003, before Marty would have left the Army. I had to do a quick edit and reloaded the chapter. Fascinating!
Anyway, Chapter 6 is up now, or will be shortly. Enjoy!
