Most Russian infiltrators sent forward never reach Ukrainian lines, a Ukrainian senior lieutenant with the call sign "Alex" reported. Russia's offensive operations now consist of small-group infiltrations, since the army cannot gather enough men for local pushes.
Russian assaults now "a great rarity"
The Ukrainian officer wrote on his Telegram channel that Russian frontal assaults have largely disappeared from active sectors.
"Right now, enemy assault operations are a great rarity," he wrote.
Russian forces now rely on infiltration — small groups of two or three — pushing covertly into Ukrainian positions.
According to Alex, 60-70% of these infiltrators die before reaching the direct line of contact. The figure underlines what Alex describes: Russian troops sent forward without enough numbers to consolidate any ground gained.
From massed assaults to two-man teams
Six months ago Russian forces could still mount regular assaults — though armor was already rarely used in offensives by then. The transition to small-group tactics reflects the Russian army's inability to gather enough personnel even for limited pushes.
"The Russians chose the most covert and deepest possible entry through our forward positions, which haven't formed a continuous line on either side for some years now," the Ukrainian officer wrote.
The lack of continuous lines on either side is what Russia exploits as its main offensive method.

Tactic losing effectiveness
The infiltration approach is not always effective for Russia, Alex's assessment suggests. Russia cannot accumulate enough personnel to consolidate any local gains that the surviving fraction of infiltrators might secure. The current Russian tactic is "gradually losing effectiveness," he noted, with advance rates minimal and the manpower deficit growing more visible.
