.475 A&M Magnum
Of course totally different mindset, I mean the Ukrainians use a camera instead of a human. Just pointing out that this not a new naval tactic. Sinking enemy vessels with another on a one way mission has been around since man started fighting on the high sea. Fireship's, spar torpedoes, manned torpedoes are just some examples and tactics to defeat such threats have been around for a long time. It's just amazing that it has happened so many times to the russians recently. You could probably time travel a frigate captain from the Nelson era to a modern russian ship and he may not be able to understand all the modern stuff but he definitely would have defended the ship from a small boat attack
The tactic may not be new, but the weapon system is, the range speed and guidance is something they probably never expected . And again they are focused on a land war , probably never anticipated a naval battle with Ukraine. Since they dont have much Navy . They got caught with their pants down . Hard learned lessons for sure.
