Ukrainian National Security and Defense Council (NSDC) information and analytical center spokesman Andriy Lysenko said this at a briefing on Tuesday, a Ukrinform correspondent reported.
"If the elite troops of the Russian Armed Forces are not competent with topography and cannot find their way on the ground, then I have nothing to say about other troops and especially generals who send people to the east of Ukraine," Lysenko said.
He said that the penetration of a military unit into Ukraine was not a mistake, but a special task, which was clearly being fulfilled.
"The Russian military leadership should think about what they are doing, because there is a lot of information that the families of Russian servicemen who are sent to Ukraine do not know where they are sent, or believe that they leave for exercises," Lysenko said.
Earlier, Russian media reported, citing sources in the Russian Defense Ministry, that Russian paratroopers detained in Ukraine had crossed the border by mistake, while on patrol.
