Here's the other photo that featured in the tweet linked in one of the articles here: >>41922
The Frenchies made patrician choice when built bastions with indentations, since fighting positions are covered by the faces of the bastions. However from these pics I can't really tell if they formed those positions for the purpose or the whole fort just uniform stacked hesco barriers. And I also no idea what are those long thingies - reminding me of shipping containers - there, placed randomly everywhere, inside he bastions too in a very disorderly fashion.
Searched a little about modern field fortifications, because I remembered battle of Wanat, where an unfinished small unit combat outpost was attacked by Talibans. I found two interesting thing, a documentary was filmed with the title Restrepo (not about Wanat, but a deployment of a unit in Afghanistan), and this:

Okay, it's about "interior design" but that fortification is nowhere from Vauban's sophistication (I would expect the dude to be familiar with Vauban's work if the designs military shit, I would expect him to know a lot about all kinds of defensive buildings from the antiquity to the present).
