The longer the APU stays in Kursk region, the higher the risks — Air Force

The longer Ukraine's troops remain inside Russia, the higher the risks. This was stated by BBC security correspondent Frank Gardner.

"Perhaps the biggest one is that Russia will deploy enough forces to encircle and cut off the Ukrainian troops before they have time to withdraw. Large losses or mass capture of prisoners will negate all recent successes in strengthening the morale of Ukrainians,"the Russian Air Force Service reports.

According to a senior British military official, who asked not to be named, he was impressed by Kiev's use of "combined arms" — entering the Russia has not only light infantry, but also engineering, artillery and other auxiliary units. However, he warned that in response, Moscow, enraged by the encroachment on its land, could respond "with a vengeance."
