ISW names possible reason for Russian offensive failure in northern Kharkiv region

This is stated in a report by the Institute for the Study of War (ISW).

Analysts note that Russian troops began their offensive in northern Kharkiv with limited forces and have not yet deployed significant reserves there, leading to a slowdown in their advance.

"This decreasing tempo is likely presenting Ukrainian forces with tactical opportunities to counterattack, although Ukrainian forces are not yet conducting a limited counteroffensive operation that aims to push Russian forces completely out of northern Kharkiv region," the report says.

Experts add that the scattered Russian units in northern Kharkiv and the indecision to involve available reserves suggest that Russian troops are likely trying to build up their Northern Grouping of Forces before intensifying their offensive.

Reports indicate that at the start of the offensive on May 10, the Northern Grouping of Forces had about 35,000 troops in the border area, while Ukrainian sources claimed the Russian military intended to concentrate 50,000 to 70,000 troops there.

Experts suggest that Russian forces likely launched the offensive ahead of schedule with insufficient personnel, hoping to gain ground before the arrival of US military aid complicates their efforts.

Therefore, the premature start of Russian operations likely undermined their success in northern Kharkiv.

At the same time, ISW experts emphasize that Russian troops managed to surprise Ukrainian forces on May 10 and achieve tactical successes in less defended areas.

• According to the Ukrainian General Staff, as of late evening on May 25, the total number of Russia's offensive and assault actions along the entire front line increased to 99. The Pokrovsk direction remains the hottest point on the front line.
