I stumbled on this and thought some might be interested, the further down you scroll the more interesting it gets.
forgive me if this is in the wrong section but move it if necessary.

Nice...Been 20 years since I looked at this FM. I still have a hard copy from my time in service in the 80s/90s and comparing the two, the changes are significant.

While comparing the two, I also came across several decks of Aircraft/Armor recognition flash cards that TASC distributed to us grunts back in those days...some of which doubled as playing cards.
