With Western leaders - including Sir Keir Starmer - shifting rhetoric towards suggesting a negotiated settlement is now the way forward, every inch of territory could prove pivotal for both Moscow and Kyiv.
In this post, we're looking at the state of play on each of the fronts.
The big picture
We'll start with a wide view of the conflict.
Russia controls more than 110,000sqkm of Ukrainian territory, according to a leading thinktank.
Donbas region
Moscow's forces continue their advance towards the crucial logistics town of Pokrovsk, with the Russian ministry of defence regularly claiming village after village in the area.
Ukraine's Kursk invasion
Ukraine continues to defy experts and is still holding considerable ground in the Russian region of Kursk.
In recent weeks, Russia has called on some 12,000 North Korean troops to join a massive effort to reclaim the territory, seen as crucial in any future negotiations.
Ukrainian commanders have reported "round-the-clock" attacks from Russian troops using armoured, light and all-weather vehicles.
Luhansk region
In Luhansk, a Ukrainian commander has claimed that Russian forces are attempting to bypass Kyiv's defences near Kupyansk (directly north of Lyman) and seize positions along the east (left) bank of the Oskil River.
The Institute for the Study of War says Russian forces have continued offensive action in the region but have not made confirmed advances.
Russian forces also maintain their positions inside Kharkiv, having opened a second front back in May - but as the map shows, no considerable progress has been made.
Zaporizhzhia region
Finally, in Zaporizhzhia, reports of a massive Russian offensive are yet to manifest into reality.
Military bloggers claim the offensive will begin at an unspecified time after Thursday.
Fighting continues, but there have been no meaningful changes to the frontline.
