I read a post that referred to an article written about the Vietnam War in the OnlineEXTRA section, but I couldn't find it earlier today. With a bit more searching I found the link to the article on the current issue page.
For anyone else having trouble finding this, here's the link to it...well at least to Part 1 of 5 of the article. There are actually five parts to this article!! Very impressive!
The Vietnam War for the modeler (1945-1975)

Now I'm off to do some reading...
BTW - I personally can't comment yet since I haven't read it, but if you like the article, make sure you let FSM know so they'll keep the good stuff coming.
