Despite the changes in warfare, Russian forces retain the ascendancy and are making slow but steady advances in the east and north of Ukraine. Russia has also caught up in UAV technology after falling behind early in the war, according to military analysts, and like its enemy is churning out drones domestically at a rate of millions a year.

A coalition of Ukrainian hackers breached and wiped systems belonging to Gaskar Group, a Moscow-based drone maker.

The facility reportedly manufactures batteries for missile guidance and glider modules, including for the Iskander system and cruise missiles, which Russia has been increasingly using to target Ukrainian cities.
