The diorama is loosely based on the above photo. My research has been inclusive regarding where this photo was taken and what unit is represented, However, it may be looking down Duy Tan Street, across from the MACV compound and representing Bravo Company1/1 Marines, which was a provisional unit consisting of the headquarters element and whatever Marines they could scrape together.
Here’s an overview shot taken while developing numerous mockups. It’s not the final layout.
Here’s a view of the base, groundwork, fence, and foliage.
