The Unmanned Systems Forces reported these results and released a video report of the August campaign by the 14th Unmanned Aerial Vehicle Regiment, aimed at reducing russia's oil refining capabilities.
"The damage caused a significant decline in oil refining capacity, disrupted petroleum product supply chains, and led to fuel shortages across russia," the statement reads.

The Unmanned Systems Forces reported that this has already undermined russia's ability to maintain efficient logistics, rotate troops, and execute large-scale maneuvers.
The following russian oil refineries were affected:
- Ryazan Refinery;
- Rosneft-KubanNefteProdukt Refinery;
- Afipsky Refinery;
- Saratov Refinery;
- Volgograd Refinery;
- Syzran Refinery;
- Kuibyshev Refinery;
- Krasnodar Refinery.
The strikes on oil refineries have also left 6.4 million tons of crude oil idle, which russia cannot use for its own needs.

"Systematic strikes on key strategic targets of the aggressor country will continue until russia ends its armed aggression," the Unmanned Systems Forces stated.
Earlier Defense Express reported that Ukraine has been systematically striking major russian refineries at distances of up to 1,000 km.
