| | Security Barrier |
 | | Each mile of barrier requires the excavation of 230,000 cubic yards of soil; the laying of 12,000 square yards of asphalt, and the installation of 80 sensor-detector posts, 600 anchor posts, 6,000 square yards of wire fencing, 26,000 yards of barbed wire, and truckloads of other material. |
 | | The Israeli model includes a number of sections composed of concrete wall 10 meters high: such sections will most likely be unnecessary in an American security barrier, so it's possible that the average per-mile cost of an American barrier would be less than that of the Israeli barrier. |
 | | While it is equally likely that such a contiguous security barrier would not be necessary and the roughest terrain would not need to be partitioned, for the purposes of this feature I've ignored the issue of terrain entirely and assumed a contiguous barrier in terms of cost. |
