I have been seeing some earth filled structures in pictures of the events in Iraq. It took a while, but someone finally told me they were called Gabions. One company is calling them, "Geocomposite cells". I am searching for detailed schematics of standardized protective designs using geocomposite cells and pultruded fiberglass structural members, of which, eight such designs being incorporated into Army Engineer School officer basic programs??? How are the gabions tied together, how high can they be stacked, and how to enclose the roof with dirt on top, two or three feet high?

Here is some internet research:

Geocomposite cells

"Protection. Conventional protective structures create logistical burdens
because they are bulky, heavy, and labor-intensive to build. ERDC has
developed modular protective structural systems that use geocomposite
cells and pultruded fiberglass structural members. These systems are easy
to emplace and provide superior stability with predictable ballistic
protection."

"Geocomposite cells are heavy-gauge wire panels, lined with lightweight geotextile fabric, and connected in collapsible rectangular cells that can be transported at about five percent of their expanded volume. Once expanded and filled with soil, gravel or other materials, the cells provide two- to four-foot-thick walls for protective revetments, bunkers, observation posts, and fighting positions. The wall's energy-absorbing capacity provides a high degree of ballistic protection against small arms,
mortar rounds, and artillery fire."

Someone told me that the previously discussed Engineering Structure being used in Iraq is a Gabion, used during the the American War of Northern Aggression or War Between The States...
Gabion. A wickerwork cylinder filled with earth and used to strengthen ramparts and provide entrenchments.

GABION: Large cylindrical basket made of woven twigs and open at both ends. Gabions were used to reinforce earthen fortifications and to repair damage to works caused by artillery fire. After the gabion was put into position it was filled with earth allowing it to protect the defenders against small arms fire.

GABIONNADE: A parapet built of gabions.

gabion - wicker or wire basket of earth or rock

Gee, you think this might be the mother of all Gabion orders??? qty
100,000 These may be what we are seeing in Iraq, Jordan is next door...
