Russian heavy artillery — the Kremlin’s deadliest weapon against Ukraine — is still a superior force that has no mercy. Almost six months into the full-scale invasion, Russian advances remain generally stalled. But despite much effort with Western-provided advanced weaponry, Russia’s artillery force is still inflicting heavy losses on Ukraine and goes unanswered much too often.

Counter-battery fire, the tactic of hunting for and firing at the enemy’s artillery pieces, remains a weak spot in Ukraine’s military.

The Russian military indeed enjoys very strong numerical superiority. Ukraine, in turn, often lacks proper organization of counter-battery activities on the battlefield. It also falls short of qualified top-level specialists.

As a result, Russian artillery continues to devastate Ukrainian lines, causing Ukrainian infantry to pay an inflating price in blood.

Russia’s numerical superiority, and its endless munitions stock, the result of decades of Soviet production, have had a devastating effect on the course of the war. Russian tactics of rolling artillery barrage, simple but brutal and overwhelming, have paved the way for Russian infantry through charred Ukrainian ruins. It has left many cities in ashes. The disproportion between the number of Russian and Ukrainian pieces deployed to a particular front line area can go as far as 10 to 1.

According to estimates by Ukrainian artillery commanders polled by the Kyiv Independent, daily Russian munition expenditure in Ukraine’s east has been reduced from nearly 12,000-15,000 rounds to nearly 5,000-6,000, quite a relief to Ukraine’s military. The fight between the two nations’ artillery forces has been beyond brutal.

The progress was notable, but the introduction of superior Western systems has not brought radical changes in Russian superiority. Russian artillery is still extremely overwhelming and deadly as it continues to shell its way through Ukrainian defenses with extreme power. Yet another wake-up call occurred on Aug. 2, just days after the Russian-led militants launched a massive offensive in the town of Pisky, a ruined suburb just northwest of occupied Donetsk next to the city’s destroyed airport.

Amid fierce hostilities, Serhiy Gnezdilov, a squad leader with Ukraine’s 21st Motorized Infantry Battalion Sarmat, published a headline-making post on his Facebook page.

The soldier’s message, full of desperation and anger, describes the horrific situation in Pisky, attacked by Russians.

Within less than 24 hours, according to Gnezdilov, Russian artillery fired nearly 6,500 rounds upon Ukrainian defenses in the town. “It’s beyond one’s understanding how some of our infantry manages to survive under this burst of enemy fire,” he wrote.

Russian artillery methodically destroyed Ukrainian concrete defenses without facing any resistance from the Ukrainian side. Ukrainian counter-battery was not working at all, according to the message. “It’s a f*cking slaughter in which the battalion personnel is just deterring the offensive with their bodies,” the soldier wrote.

Speaking on the condition of anonymity, serving Ukrainian artillery officers polled by the Kyiv Independent admitted that Ukrainian counter-battery activity remains largely problematic, mainly due to the lack of effective top-level organization.

In many cases, Russian successes were ensured not by its overwhelming advantage but by a problematic Ukrainian counter-artillery reaction. “The infantry has paid for those flaws with its blood,” a Ukrainian artillery officer told the Kyiv Independent.

tl;dr: SSDD, cuckraine losing.
