This talk is mostly BS. It is just photo recon flights, with camera's, talking pictures from 10,000 feet. This works for large targets like cities and towns that cannot move. The WWII 8th Air Force was able to find and bomb German cities from just overhead photos. But you cannot find and strike smaller and mobile targets like enemy infantry, or enemy leadership. Despite a lot of technological progress since WWII, our " over-the=horizon" capabilities are no better than they were back in 1944.
So when you hear Democrats talking about "over-the-horizon" operations on TV, know that you are hearing mostly happy talk, trying to make our pullout from Afghanistan sound less dreadful and less shameful than it really is.
