Geesh. Maybe I've been wrong about Russia. It appears that they are helping to open up the Ukranian ports for grain shippage. Yesterday, they ran one of their ships into a mine, clearing the mine:
The Russian navy appears to have accidentally blown up one of its own ships in the black sea in the latest blunder for Putin's forces. A landing craft is reported to have exploded when it hit a Russian sea mine.

However, I'd recommend that they use mine sweepers. They are much cheaper than sacrificing a ship. But again, well done Putler!
