The discussion of Hesco vs concrete barriers is an interesting one, and I think a lot of the other comments handle it well.

The thing I was wondering while reading the article is what will they do after the fighting is done?

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

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

I suspect lots of them will remain until they fall apart, especially in situations like lining highways. I bet that the walls in the city, and the enclaves formed by them, will be affecting the culture off the city years after the conflict is done.
