Yes, now that you've completely changed what you said, from... They don't rely on any kinetic energy at all to penetrate to... "which is expelled at high velocity from the explosive and then penetrates through kinetic energy" I agee. But these projectiles only work under 2 conditions. (1) They have something very solid behind them, like the ground, or a metal gun, or (2) they are hurling toward the object at great speed. And if the drones are simply going to be kamikaze diving from 1000 feet above, almost anything you attach to it will cause significant damage. However that'd be a pretty low-precision maneuver, and sort of defeats the purpose of all those weeks spent training to perform image recognition.
