Ukrainian forces face shortages of artillery shells and have to scale down some military operations due to a decrease in foreign aid, Brigadier General Oleksandr Tarnavskyi said in a comment for Reuters on Dec. 18.
"There's a problem with ammunition, especially post-Soviet (shells) - that's 122 mm, 152 mm. And today, these problems exist across the entire front line," said Tarnavskyi, who commands the Tavria group of forces.
The general called the shortage of shells a "very big problem" and connected it to the decrease in foreign military assistance.
"The volumes that we have today are not sufficient for us today, given our needs. So, we're redistributing it," the commander added, explaining that the military is scaling down its tasks as a result.
Moscow is also dealing with ammunition problems, the general said without providing further details.
Russia's advantage in artillery shells has long been one of the key obstacles pointed out by Ukrainian commanders.
Moscow's defense industry may be able to increase its production to 2 million shells annually in the next few years, an undisclosed Western official told Reuters in September.
Domestic industry is also not Russia's only source of supplies, as it allegedly managed to secure at least 1 million rounds from North Korea.
This number is still not sufficient to cover Russia's war needs, as its troops reportedly fired between 10 million and 11 million shells in the first year of the war.
In turn, Western deliveries play a major role in Ukraine's artillery arsenal, namely the 155 mm NATO-standard rounds.
The EU pledged to deliver 1 million shells to Ukraine by the spring, although many worry that the plan will miss this deadline. Around half of the number is expected to be delivered by the end of this year.
