For those who don't follow the Ukrainian summer offensive too closely, it has now entered a new stage. The Ukrainian troops have finally made their way through the minefields and have entered those long Russian trenches east of Robotyne. Those trenches run more or less unbroken for almost 40 km east to west up to 10-15 km behind the most forward Russian positions and if The Ukrainians can capture those, they may well liberate more than 400 km2 og territory in one big swoop and if they're really, really lucky, they may also isolate and effectively surround several thousand Russian troops.
Some reports suggest that the Russian army has made the mistake of engaging far too many troops in the battle. That may sound a bit strange at first but a trench is rather narrow. When both sides are in the same tench, too many soldiers only get in the way of each other.
The offensive started with the western strategy of rapid maneuver warfare but as we know, that didn't work too well against defense lines as solid as the Russian ones, especially since they don't have air supremacy. They already knew of course that the eastern style brute force strategy wouldn't work so they came up with a brand new one, called "strecth, starve and strike" instead and it seems to be working very well. You start with the old Russian/Soviet style, attacking everywhere to force your enemy to spread out their troops. But then, rather than keep on pushing, you launch a massive attack against the supply lines to one sector of the front. FInally, when that sector is sufficiently starved of resources, you strike. It's actually a variant of the good old method of finding and exploiting the enemy's weak spot except rather than find the spot, you create it.
Only 121 days left before we know if my theory holds.
