Russian troops regularly test modified ammunition. They use Kharkiv as a training ground for their exercises, according to Oleh Syniehubov, head of the Kharkiv Regional Military Administration.
"The enemy does not stop and constantly tests modified ammunition, using Kharkiv as a platform for its exercises," said Syniehubov.
He noted that the Russian army tried to adapt and use all its stockpiled ordnance against the Ukrainian civilian population.
"We had the first strike on Kharkiv on Sunday, on the territory of a private school. It was a KAB-250. The ammunition had wings and a GPS module," the head of the Regional Military Administration said.
Syniehubov also pointed out that it became increasingly expensive and difficult for the enemy to use missile systems such as Kalibr, which cost about $10 million.
Therefore, the Russian army has started using the UMPB D-30 (Unified Multi-Purpose Gliding Bombs) for strikes on Kharkiv. Their cost is approximately $100,000, and after modification, perhaps a little more.
