Every generation of veterans has its own slang. The location of deployed troops, their mission, and their allies all make for a unique lingo that can be pretty difficult to forget.

That same vernacular isn’t always politically correct. It’s still worth looking at the non-PC Vietnam War slang used by troops while in country because it gives an insight into the endemic and recurring problems they faced at the time.

Here are some of the less-PC terms used by American troops in Vietnam.
