 Ukrainian troops face artillery shortages, scale back operations. Frontline Ukrainian troops face shortages of artillery shells and have scaled back some military operations because of a shortfall of foreign assistance a senior army general told Reuters. Brigadier General Oleksandr Tarnavsky was speaking after Republican lawmakers held up a $60 billion US aid package and Hungary blocked 50 billion euro funding for Kyiv as it battled Russia's invasion. There's a problem especially post-Soviet shells that's 122 mm, 152 mm. And today these problems exist across the entire frontline, he said in an interview. Tarnavsky said the shortage of artillery shells was a very big problem and the drop in foreign military aid was having an impact on the battlefield. The volumes that we have today are not sufficient for us today given our needs. So we're redistributing it, we're replanning tasks that we had set for ourselves and making them smaller because we need to provide for them, he said, without providing details. The comments underline Kyiv's reliance on Western military aid to fight Russian troops along a 1,000-kilometer front nearly 22 months into the biggest conflict in Europe since World War II. Russian forces also face ammunition problems, Tarnavsky said, without specifying their nature. Weary Ukrainian troops on the southeastern front have gone on the defensive in some areas but are tracking to attack in others, he said. Ukrainian forces still expect victories but would benefit from reserves to rotate and rest them, he said. In some areas we moved to defence and in some we continue our offensive actions by manoeuvre, fire, and by moving forward. And we are preparing our reserves for our further large-scale actions, he said.
