Since launching a surprise attack last week, Moscow has been unable to push Ukrainian troops back after they advanced up to 30km into Russian territory and are now in control of about 28 settlements.
As you can clearly see on the map, the front is in Ukraine. One operation has pushed part of it into Russia from the Ukraine, but the front line remains on their home soil. The goal of the operation that pushed into Russia is to remove the foreign invaders from the Ukraine, so its purpose is also to support the fighting that exists on the front in the Ukraine, their home soil.
