So far, this offensive has been ongoing for more than a month and nothing much has come of it, they have not reached the first line of defence. I don't think they have committed most of their forces and I think they are waiting for the first line to be reached and a weak point to be established before launching the main effort. But if they are unable to reach the line and create a weak point then the offensive may be dead before the main effort can start.

The Ukrainian attacks around Bahkmut seem to be more successful. Maybe this will draw Russian forces from the south.
