Sheer quantity can hit. Targeted shots are dodgeable with high probability from 3m+ distance. Whether this is economical to the defender vs the attacker is the question.
Hmm, you're thinking that if a gun is pointed at a drone and launching grenades at it at 500 meters per second, the drone can dodge the grenades with high probability if it's 3 meters or more away from the gun? 5 meters is 10 milliseconds, and the assured kill radius of the grenades is presumably at least 200 mm; for the drone to move 200 mm in 10 ms it needs to average 20 m/s in an unpredictable direction, which means it needs to accelerate to 40 m/s in 10 ms, 4000 m/s/s, 408 gees. How do you propose for the drone to accelerate at 400 gees, other than being hit by a bullet?
Forgive me, second-hand calculations with similar assumptions but which forgot the t^2 square root on d=1/2at^2. Reran them and you are correct.
Racing drones routinely do 6Gs. So ~60m/s/s acceleration. With your above assumptions that's then about a 40m distance needed for a drone to juke out of the way of the shot. Thank you very much that's an important difference.
