All of these are solved or solvable problems and aren’t impediments in practice. For comparison: a single unguided artillery shell costs $5,000. A guided shell starts at around $20K and fancy long-range versions can exceed $100K. It takes on average 2-15 shells per kill. If you had a > $100K budget “per attack” and were making drones in large volume production, then you can easily beat the costs of traditional weapons. Drones are cheap and can deliver their payloads with incredible precision. Not “150 foot radius accuracy”, but “aim of the left foot of the soldier” accuracy. It’s a whole new ball game.
