Russia gathers over 100,000 soldiers on the Lyman-Kupiansk axis

So you're saying that they're all concentrated in one relatively compact area then? Hmm...

Russia is concentrating "more than 100,000 personnel, more than 900 tanks, more than 555 artillery systems, 370 MLRS" in the Lyman-Kupiansk direction, according to Serhii Cherevatyi, spokesperson for Ukraine’s Eastern Military Command.

Cherevatyi said on television on July 17 that Ukrainian soldiers are currently holding the defense.

Kupiansk was liberated in Ukraine's surprise counteroffensive in Kharkiv Oblast in September 2022. Lyman, in Donetsk Oblast, was liberated just weeks later. https://kyivindependent.com/military-4/
