Sand.

This is coolbert:

From the Iranian Internet web site PressTV this item.

Reminds me to an extent of the Morocco Western Sahara sand berm wall.

"Israel erects sand barrier amid fear of Gaza missiles: Video"

"Israeli construction workers are building a sand barrier on the border between the Gaza Strip and the occupied Palestinian lands."

"The Israeli military says its so-called Southern Command’s engineering unit has been erecting a sand barrier near the fence between the occupied territories and the besieged Gaza Strip."

DESIGNED TO COUNTER AND PROTECT ISRAELI PATROLS FROM DIRECT FIRE ANTI-TANK GUIDED-MISSILE [ATGM] I WOULD PRESUME.

Watch the video and observe the armored bulldozer with the slat armor. Slat armor able to defeat the shaped-charge round of an ATGM. Crew has more than adequate protection. A combat engineering vehicle most formidable.

The Western Sahara sand berm found to have been effective. Indeed, built in part with Israeli expertise way before the Gaza sand wall!
