Via Infoniac: The New Jersey-based company Dynamic Defense Materials has developed an armoured wall system that can be assembled like Lego, in less than an hour, to form a 6.5 metre high bullet-proof wall.

For me, it’s interesting to see the architecture of control and defended territory being so flexible and responsive. Fourteen of these have been bought for Afghanistan, at a cost of about US$60,000 each. I’d be very interested to know their usage patterns, and how permanent the constructed structures are. It’s a surprising reversal if the marines are temporarily poaching space within dangerous enemy territory, when their traditional role is seen as occupying force.

There is something of the ultimate cushion-and-duvet cubby-house reassurance in this. The safe womb, or the pocket of controllable space to call your own.
