US occupation of Iraq in the context of "Concertainer"

A Hesco bastion,also known as a Hesco barrier, and formally Concertainer, is a gabion introduced in 1989 and primarily used for flood control and military fortifications. It is made of a collapsible wire mesh container and heavy-duty geotextile fabric liner and is used as a temporary to semi-permanent levee or blast wall against small-arms fire or explosives. It has been used in military applications in Iraq and Afghanistan.
