Some pics of anti-tank elements. Also some pics about "how to do it" , enought to see the way to build it (with my english i cant do a tutorial)
-- Take some poliestirene and cut a small cube (3x3 cm base)
-- Cut it, 3x3 cm base and 3 cm tall (the walls with some inclination)
-- Give it texture with a mix of white glue, water, sand and aquaplast (white conqrete??)
-- Paint it with grey spray, and dry brush of a light grey
