... can be found in a handbook for commanders and other U.S. military personnel published by the U.S. Army last year.
It includes a wide variety of interesting and peculiar details,
including an introduction to German wine and beer.
"German wine categories are more complicated than German beer
categories," the Army guide says. "There are three types of wine and
three colors."
It also includes advice for how to handle delicate interpersonal
situations.
For example, if two persons pledge brotherhood ("Bruederschaft") over
drinks and switch from using the formal you ("Sie") to the informal
you ("du") and one of them later comes to regret the intimacy -- what
then?
"If an unhesitating 'Sie' is used [by one person] at the next
encounter following a Bruederschaft drink, the other person should
also revert to using 'Sie'."
