markh166 provided one reference if you're looking for Vietnam era loose parts.
I recommend perusing/searching the loose parts section from the known 1:6 vendors.
There is no active/regularly offered 1:6 Vietnam era/themed items from any 1:6 brand asides from a.c.e. Workshop, but their offering schedule is not consistent and there are long periods of waiting before anything new is offered.
Your post/question is too broad. Refine your question further and I recommend doing some leg work on your own in searching.
Members here will help . . . those who help themselves who are truly interested.
Don't take the reply the wrong way, but you probably will and that's on you.
We all learned the hard way when it comes to searching and asking questions. Just don't expect anything/everything to be answered at your beck & call. If you are, then you're in the wrong hobby.
