Why are military ships so difficult to attack from distance?

Sure, but giving that this occurred during the video and knowing that the army has had so many problems, I wouldn’t be surprised if the frequency is much higher.

Sure, I think so. But conscripts and poor motivation would likely make it worse.

Besides the anti-missile/aircraft/drone missiles and close in gatling gun systems; there are electronic counter measures to mess with incoming guidance, high powered LASERs are almost ready, and decoys from simple aluminum chaff to floating/hovering false targets like the Nulka -

and Naval Decoy IS300

Dither is a legit technique for improving the accuracy of mechanical gauges.

…[O]ne of the earliest [applications] of dither came in World War II. Airplane bombers used mechanical computers to perform navigation and bomb trajectory calculations. Curiously, these computers (boxes filled with hundreds of gears and cogs) performed more accurately when flying on board the aircraft, and less well on ground. Engineers realized that the vibration from the aircraft reduced the error from sticky moving parts. Instead of moving in short jerks, they moved more continuously. Small vibrating motors were built into the computers, and their vibration was called dither from the Middle English verb “didderen,” meaning “to tremble.” Today, when you tap a mechanical meter to increase its accuracy, you are applying dither, and modern dictionaries define dither as a highly nervous, confused, or agitated state. In minute quantities, dither successfully makes a digitization system a little more analog in the good sense of the word.

Moskva had a very highly effective automated detection system. When it detected the incoming missile, the system responded by producing a very loud sound and bright lights.

They’re still working on the part where they detect the missile before that point, though.

Heh.
