Except…. when it IS a missile

Ukraine’s newest drones are essentially cruise missiles with remote human guidance.

The difference in the size of the boom is just a matter of scale.

And to that point you have to ask; would you rather have one big boom or three smaller booms? Now ask; what if there is AA systems in your path that are going to intercept 1/3 of your missiles?

One smaller boom is better than no boom at all.
