Hesco barrier
n.— «Iraq and Afghanistan are dangerous. Real dangerous. Mortars, RPGs, snipers and car bombs, you name it. Imagine you’re a soldier in the occupying army. How can you even sleep at night with all those munitions aimed at you? The answer: Hesco barriers. Take a collapsible wire-mesh and canvas screen and fill it with dirt, stack and repeat. For $700 per 5’x4’x3’ box, plus some muscle power, you’ve got yourself an instant castle wall that can absorb all but the biggest blast.» —“Danger Room: Top War Tech #10: Hesco Barriers” by David Axe Wired Blog Network May 29, 2007.
