They just took out 40% of Russian oil export capacity.
>They just took out 40% of Russian oil export capacity.
Yes, Ust-Luga and Primorsk. Very successful hits. Painful for Putin. Yet it isn't a knock-down. Russia is like a big drunk guy in a street fight - just delivering painful blows to him doesn't help, you have to deliver a knock-out blow, and unfortunately Ukraine still seems far from it.
>Both countries do the type of attack drone clustering you suggest
Ukraine still isn't completely there. They do attack Russia with up to 200 drones/day. They seem to never cluster more than a few, and the drones they are using are comparably small - 50kg warhead - and slow, 100+ km/h, almost always less than 200km/h. So they are easy to intercept/shoot down, almost never penetrate Moscow air defense, and do noticeable damage only when hitting flammable targets like oil/gas industry related.
