The wall will be 1600km long, there's no need to concentrate anywhere, there's no way the Americans will be covering the wall with troops or anything like that, they will have hundreds of kilometers of concrete wall in the middle of nowhere, which they can exploit as a shield to block the Americans from seeing what they are doing and then acting to interdict it, it's a big screen, which enables a tunneler to operate undetected and so not interdicted.StCapps wrote:Yeah but if they concentrating all their tunneling in areas around the wall the Americans will know that and can plan accordingly. Bait them into tunneling in areas where they are easier to catch by placing the wall there. If you know where they are going tunnel is it really that much harder to find them? If you have problems seeing under the wall put security measures in place to help to cover that blind spot. If that makes the price tag too high in some portions, then don't build the wall there. Should still reduce tunneling, not increase it, unless I'm missing something.
Without the wall, you'd spot the activity very quickly, they would stand out like a sore thumb, but with the wall, they have a barrier which they can use to hide behind while they work.
