Thats some bug-out.
Why do that when the F15s can go in from far off?
Maybe someone needed flight hours (not likely) or it was used for training purposes (possible). Would make sense to blow up in place if it costs more to haul it out than replace it. But from the air? I’m guessing training.
An F-15E strike isn’t cheap. There’s the ordnance, fuel, tanker & optional jammer support. Plus your putting at least 2 airman at risk in a heavy SAM environment. A few pounds of C-4 and some Det Chord will get the job done if you have sufficient time to set the charge.
