In this context I would sacrifice multiple aircraft to ‘taint my the enemies training data with solutions which are a disadvantage in a future fight scenario.

That's why this probably won't actually be in use for many decades. You need something a bit closer to AGI than what exists now. Until then, you'll probably have limited use cases, maybe where movement and obstacle avoidance are autonomous but everything else is programmed or remotely controlled.

You could imagine small, agile flying assassination drones which can navigate cities and houses to kill targets with short-range projectiles. Very Black Mirror-esque, but far more ethical than the current approach of Call of Duty 4-style blowing up a big patch of land from the clouds with a Hellfire missile, including all the civilians in proximity.
