> Will the barriers and walls be left in place or dismantled?

I was looking at satellite images of the area my FOB was at in Fallujah - no sign of our presence. We had double stacked hesco all over the place, as well as Texas and Jersey barriers on the road.

> Is it easier to take down or move concrete vs Hesco?

Easier to take down hesco (boltcutter and a knife), impossible to move. Concrete is easy to move with common construction equipment, I'm sure the people of Fallujah found a new use for the barriers pretty quickly.
