The problem is that each 30mm projectile costs ~5k. Not a good trade off if you swarm it with $300 Chinese drones. And as soon as it starts firing, artillery will start raining down on it. Plus, the Russians have already demonstrated the ability to attack AA systems from multiple sides to get through the blind spots. Any attempt to cluster multiple AA guns or radar systems will make for an incredibly attractive target. Modern production lines can make what, a few hundred of them a year at best? Russia has purchased several thousand drones from Iran alone last year, and they have supposedly produced several hundred thousand lancets.

The US desperately needs to stop feeding the MIC and Wall Street and to reindustrialize the US economy, because we are simply not able to produce anywhere near as much missiles, shells, tanks, etc to fight the war the US wants to fight. The current combined yearly shell production capacity of Germany and the US is less than half of Russia’s alleged production capability, and they just signed a deal with NK that will likely increase their production capacity by a good 50% at least.
