King, I too hope Larry answers your Q. I can provide a good clue that has not come to me from classified sources.
Short of tactical nuclear weapons, we have some large-area destructive bombs. I've heard that some work not only by blast but by oxygen deprival. The key point is they kill everything within a fairly large radius. One, I think is called the MOAB (perhaps a nickname -- "mother of all bombs"). The earlier, Viet Nam version could be delivered by a C 130 (per a pilot who did so). Obviously, assuming a fair number of proper aircraft were available, we could have killed whatever was in a fair amount of real estate.
I can also speculate that some of those likely might have been friendlies.
