Another solution to the same problem has been used in Iraq. The GPS guidance on US missiles is so good that in some cases our planes have dropped concrete bombs. These bombs obviously don’t explode but they are a little rough on the mud brick buildings that are prevalent in Iraq. In some cases the targeted buildings have been completely destroyed while doing little or no damage to neighboring buildings.
I think that technique was pioneered in the first Gulf War, because Sadaam kept parking military vehicles next to historical sites he knew we wouldn't bomb.
But one thing not mentioned in this article is that this gps guided artillary is extremely cheap compard to precision bombing from a manned aircraft. This aspect changes our military tactics substantially.
Isn't it amazing? Technology has come full circle. We're essentially back to throwing rocks at the bad guys.
