The Russians are pursuing three objectives with the invasion of troops in the north of Kharkiv. The first is an attempt by the Russians to form a kind of buffer zone. This follows from the increasing number of attacks on Russian towns near the border, such as Belgorod. (...)

Secondly, Russia has extended the front line by another 200 kilometres. This puts Ukraine under pressure, as it now has to deploy its precious reserves not only in the Donbass, but now also north of Kharkiv. This is a tactic of war of attrition: The Russians are tying up the Ukrainians in additional places, making it more difficult for them to manage the entire front.

The third intention is to create a deployment zone for future attacks, a kind of staging area from which the Russians can then theoretically attack in the direction of Kharkiv.
(...)
When the first 180,000 shells arrive from the Czech Republic at the end of June, that will be enough for 30 days if 6,000 shells are fired per day. The Russians, however, fire 20,000 to 25,000 shells a day.

It is reported since weeks that Russia assembles a new army group in Russia near the border, that is planned to consit of at least 100,000 men, of wich 60,000 seems to be ready and who have staged the attacks near Kharkiv.
