- Ukrainian forces launched a surprise offensive into Russia’s Kursk region last Tuesday.
- They have captured around 1,000 square kilometers of Russian land so far, Kyiv’s top general said.
- That figure is almost as much territory as Russia has seized in Ukraine this year.
Because its a big tactical advantage that they opened a gaping hole in Russian defensive lines.
Defenses are strongest in the direction they are facing. They are very weak from the sides and even worse from the rear. (Ukraine now has a lot of Russian rear it can take advantage of, from Kursk)
If Ukraine has the manpower they could take this little bit of land, manoeuvre around the Russian lines, wreck their shit and get back a lot of land that was stolen from them.
Just to underline what this comment is saying: this type of breakthrough was the wet dream of WW1. The race to the sea, where the western front was established, was based on finding a flank and turning it. That was the objective of most warfare up to that point, and it ended because they ran out of ground on which to turn a flank. Then they couldn’t meaningfully break through the defenses (or layers of, to be more accurate), like we see Ukraine doing in Kursk. If they turn the flank, they’ll have routing russians for days, and have achieved maneuver warfare again.
