Did you ever think what it was like in the WWII days when people were stationed in foreign countries? I never thought much of it but if you really get down to the finer details, you had tens of thousands of men living in other countries that have no idea what life and culture is like there. It could leave a lot of awkward encounters if you don't know what the people were like.
This image is a very cool find. It's from a booklet the US Army would give to soldiers that were stationed in Greece. It details the Do's and Don'ts of how to deal with the Greek people at the time. Very cool and very interesting to see this type of historical record!
