A memory card with vital information was reportedly taken by Ukrainian forces from a Russian surveillance drone.
That drone was purportedly used by Russian servicemen to visit their military facility in the Mykolaiv region of southern Ukraine.
The film, which is currently in the hands of Ukrainian agents, has given defending soldiers new knowledge on the configuration of Moscow's forces,
leaving Russia's army vulnerable to carefully thought-out strategic counterattacks.
A portion of the drone footage that was collected has been posted on social media. In the footage,
a drone can be seen flying above what looks to be a Russian military facility,
which has numerous armoured vehicles and buildings that look like warehouses.
