In addition, 2,155 soldiers were injured.
Skibitskiy stated in an interview, "I stress that Russian troops suffered significant losses after the signing of the Minsk Agreements, and during the continuation of the aggression of the occupying Russian troops on the territory of our state.” Skibitskiy also said that since the beginning of 2016, on the territory of the so-called Donetsk People's Republic and Luhansk People's Republic, 42 Russian soldiers have been killed.

In addition, in eastern Ukraine there is a military reserve that consists of 21 task force groups of the Armed Forces of the Russian Federation, 15 battalions, and 6 companies, consisting of more than 9,000 Russian servicemen. The activities of these corps are supervised by the General Staff of the Armed Forces of the Russian Federation, using the headquarters of the Southern Military District. At least eight Russian generals are involved in military operations in the Donbas.
