The Russian air force has been bombarding Ukrainian cities with impunity for the last ten months, dropping cruise missiles from hundreds of miles away and even dropping unguided bombs over Mariupol.
Hundreds, if not thousands, of Ukrainian civilians have been killed in these bombing raids.
The Ukrainian armed forces have decided to retaliate. The Russian bomber bases were hit by Ukrainian drones on Monday morning, 100 and 400 miles from Moscow.
The Russian defense ministry said that three Russian personnel were killed and four others were wounded by the drones.
The damage to the Tupolev Tu-22M3 bomber was confirmed by photos that were posted online. The Ukrainian garrison holed up at the Azovstal steel plant in Mariupol was carpet bombed by the supersonic Tu-22M3s.
There are 60 Tu-22Ms, 60 Tupolev Tu-95s and 16 Tupolev Tu-160s remaining in the Russian air force. There is no reason why the Ukrainians can't do it again.
The Kremlin said it had air-defenses. It said the fall and explosion of fragments caused the damage and casualties. It doesn't make the Ukrainian raid any less successful. Wrecked bombers and dead troops don't care what happens to their drones.
There are other incidents like the raids on Dyagilevo. Russian air bases have been hit by the Ukrainian armed forces since the beginning of the war.
The Russian navy fighter-bombers were knocked out in one of the most successful raids of the year.
The Ukrainians have hit Russian air bases with a wide range of weapons. In October, Ukrainian saboteurs blew up a Russian air force helicopter at an air base 500 miles from their home country.
Some of the Kremlin's most valuable assets are at risk as a result of the counter-airfield campaign by the Ukrainians. It's troubling for the Russians.
The Russian air force launched at least 14 Tu-95s with long-range cruise missiles at Ukrainian cities just hours after the attacks on Dyagilevo and Engels.
The raid was revenge for the actions of the Ukrainians. The targets were all hit.
