Typically they use a high angle and delay fusing to minimize collateral damage if something like a single building needs destroyed. This minimizes the impact of the blast on surrounding buildings. In Baghdad you can actually find buildings that were “hollowed out” but their outer structure is still standing while buildings adjacent are hardly touched. The bomb came in through the roof, blew the guts of the building out, but left the outer walls standing. It's pretty remarkable how refined the whole process is. They match the delivery platform, to the ordinance carried and marry that to an appropriate fusing and then deliver this package just right (angle of approach the bomb is released, angle the bomb hits the target etc) to get the desired result. They can model the actual outcome before an air strike! Before they drop those bombs they often actually already run a simulation that shows the collateral damage, the outcome of that specific ordinance delivered onto that target! The science, process, hardware and people behind all this is pretty impressive. But of course CNN thinks differently.
Its called American ingenuity.
The media is still amazed we broke the Enigma code.
