should I look at it differently Bobko?
Even a monkey can see that risk, so yes - of course.
The military command has certain reserves available to it - analysts say approximately two army corps. For stabilizing this salient that we are discussing, and for allowing the further exploitation of the dynamically developing opportunities - reserves were put in place. Specifically, we can say now that it's 3 strengthened brigades, which were previously involved in liberating Avdeevka. For a month they were resting and reconstituting, but now they have been rotated to that direction to hold the "neck" of the salient against counter-attack and hopefully widen it. These are some of the best formations available to the Russian military.
In the event, they are actually succeeding quite well at widening the "mouth" of this breach, and it's now much more safe.
Instead of a 5 km long "intestine", it's now a 6-7km by 5km rectangle. It's widening by the hour, and the point of the spear is also diverging and expanding.
Don't want to be running ahead of the train here with wild forecasts, so let's wait and see what happens.
Some people are saying Russia does not have adequate reserves to truly exploit this breakthrough, and will instead opt to slow it down and again start collecting strength for the next push which could either be designed to encircle Toretsk or push towards Pokrovsk.
Other people are saying it's all a "fixing operation" to stretch the Ukrainians thin before attacking from an unexpected direction like the Kharkov one.
I think the main aim is still just Donetsk and Luhansk... but that's me on my couch :). Kharkov seems a little ambitious at the moment.
