Yup, seems a very simple strategy so far, probing attacks all along the southern front, continued pressure on the Bakhmut area and retain the gains from last year in the northeast. The progress from those probing attacks has been okay so far, am a little surprised that there's so little SHORAD support there but I guess there's only so many gepards and air defense systems on had so probably tied up defending cities and logistic/command nodes.
I know the vaunted 'defense lines' haven't been approached yet but honestly it doesn't look like the Russians have the manpower to defend the length of those lines anyhow. The towns/cities around key intersections like Toma will certainly been defend more vigorously but I don't envision 'fortress' defense to the last man efforts if threatened to be cutoff.

I think if they reach the main M-14 coastal highway they'll have met their initial objectives as the land bridge would depend on supplies via Crimea/Kherson for everything west of any such salient. That's still pie-eyed wishing for me though, there's a lot of farmland and plenty of small towns in the 85kms to the highway and we've seen how effective those border hedges/treelines have been for defending forces.

If they get close the highway though, I don't think they'll try to take Mariupol as its too much an icon of the war so far and has overstated political value for both sides to retain, getting the port of Berdyansk would lengthen the supply routes for everything to the West, make the defense of Tokmak more difficult as forces would be needed for retaining Melitopol too. Offensively this would also enable the use of ASMs to threaten shipping the sea of Azov and seagoing drones to threaten Rostov too. Though this threat would be more useful in keeping leverage to keep the grain deal on and denying the black sea fleet another place from where to operate.

We've only seen a few of the new brigades in the offensive but suspect the others are being used as strategic and operational level reserves as well as to rotate out the current forces to prevent culmination too soon. Glad to see the western gear isn't 'tossing turret's and has been for the most part keeping the crews alive.
