The U.S. experts have shown the Russian military equipment that was transferred to occupied Crimea amid the build-up from February through April 2021.
In particular, units from the 76th Air Assault Division descended on the Angarsky training area on the southeastern outskirts of Simferopol in Crimea by rail from Pskov, supposedly for exercises, as reported by the Atlantic Council's Digital Forensic Research Lab.
The imagery of the Angarsky training area taken on April 21, 2021, showed that some of the tents on the western part of the training area had packed up and moved. It was unclear where they were relocated. Trains moving to Simferopol carried T-72B3 main battle tanks, BMD and BTR-D airborne armored vehicles, Nona self-propelled 120mm mortars, D-30 122mm howitzers, fuel trucks, and recovery vehicles, among other things.

However, SAR imagery from April 15, provided by Capella Space, revealed that the base is back in use with Russian military helicopters, such as Mi-8 transport helicopters and Mi-28 attack helicopters.
The DFRLab also reported on the scale of the Opuk training area, which turned out to be the largest collection of troops in the recent build-up.
SAR imagery of the area showed the majority of the equipment proved to be a wide variety of tanks, armored vehicles, artillery, and support vehicles, mainly from the 58th Combined Arms Army.
According to the experts, even if Russia follows through fully on its promises, the peninsula will still be increasingly militarized with the planned permanent deployment of the 56th Air Assault Brigade to Feodosia, where the brigade will be reformed into a regiment.
