The 2nd National Guard Corps "Khartia" announced that the Ukrainian Defense Forces carried out an offensive underground operation against "Vels", advancing more than 15 km into the rear areas of the enemy in the Kupyansk sector.
The grouping combined the underground attack with surface operations and drone strikes, effectively denying the occupiers the opportunity to maneuver into Kupyansk's rear. As a result of the operation, over 30 troops were captured, and Russian casualties exceeded 100.
