While not yet game changing, these advances indicate that Russia can move forward, and still intends to win the ground war. Backed by aircraft and guided bombs, Russian troops can put pressure on Ukrainian forces, who are overstretched by exhaustion and equipment shortages.
Admittedly, what Russia has been able to accomplish so far doesn’t feel much like winning. They have recaptured some important territory, though the price paid has been ruinous.
The capture of Avdiivka alone cost Russia thousands of troops and hundreds of vehicles. Still, stopping these advances from turning into breakthroughs is costly for Ukraine as well, and despite these losses, Russia is still massing forces for further offensives.
