We’ve been here before with the Soviet invasion of Afghanistan. That didn’t work out too well for them either
Hell they’ve got a sizeable amount of the western front of Russia’s army surrounded and set for a strategic rout.
Rout == uncoordinated retreat, which seems to be happening on a regular basis right now. Russian morale is really, really bad.
Surrounded / Encirclement might really be happening. Its hard to tell for sure due to the fog of war, it could just be Ukrainian propaganda, but there's so much discussion about a Ukrainian counter-push in various parts of the country.
Rout == enemy escapes, with heavy losses due to disorganization. Its a win, but not as much of a win as "Surrounded/Encirlcement", which basically is a "surrender or die" situation.
Its clear that the Russians were trying to encircle Kyiv (and Mariupol with more success). But there seems to be whispers that the Ukrainians are successfully surrounding / encircling some Russian troops.
