Look at this photo:

Then I have these drawings


Going by that, the front most ERA bricks on the pointed array of the turret should have the thickest out of the ERA brick types (as seen on skirts on the topmost photo), but they look like the standard ERA type bricks in that photo.
I know that Modelpoint has the "thick" ERA bricks, but with very limited availably and only 9 per package, it would get really expensive trying to do the side skirts with them, but I've seen photos with just the upper part of the side skirts fitted with ERA so that might be an easy way to get around that.
Then to throw a monkey wrench into this, I found this setup!


I'm hoping this is just a mockup and I can ignore it...LOL
