Thanks guys!
The blocks come from the Royal Model Israeli Concrete Roadblock set # 449

They came as plain white plaster and after I attached the wire lifting pieces I primed them up with Tamiya fine grey. I then painted light grey where the concrete is worn and broken. Then I painted the block with MM Armor Sand and lightly brushed around the worn/broken bits to show the chipped concrete. In the block with the blast hole. Well that was a air bubble that broke, so I made it look like some battle damage. A wash of MM acrylic burnt umber and a wash of acrylic light earth finished them off.
Knowing that these are Israeli roadblocks I still used them with a Bradley because, well, it was different. LOL
Thanks again for the kind words!
