Russians struggled a lot with the Ukrainian drones during the initial stage of the war. They didn't have sophisticated drones like United States to take out high profile targets stealthily. As a result suffered significant casualties. Now Rissians have realised the importance of drone tecnology and are investing heavily on it. Drones they have taken from the Iran appear to be useful and have taken out significant amount of Nato supplied hardware and vital infrastrcture as well. Their own made more technoligically superior drones like Sukhoi S-70 Okhotnik-B, may enter into the active service soon.
