#Russian Military losses

A Ukrainian underwater drone struck and critically disabled a Russian Project 636.3 Kilo-class submarine inside the Novorossiysk naval base. Ukrainian analysts say the strike effectively removes the submarine from service due to Russia’s inability to repair submarines in the Black Sea, while blast fragments from the explosion may have also damaged a second submarine moored nearby.

FPV drone warfare and Russia’s meat-grinder tactics forced Ukraine to redesign its fortifications. A new continuous kill-zone system aims to stop rapid Russian assaults through layered trenches, wider fire lanes, and anti-vehicle obstacles. This is what modern trench warfare looks like.
