According to USNI News, the Russian Navy has trained dolphins to defend a naval base in southern Ukraine.
Satellite images show that the bottlenose dolphins were released into the Black Sea inside two separate pens inside the harbor.
According to USNI, dolphins have historically been trained to look out for enemy divers in the US and Russia.
The marine mammal training program that was started in the Soviet Union is still going strong. After the fall of the Soviet Union in the early 1990s, the unit was taken over by the Ukrainian military.
According to USNI, the Russian Navy uses whales and seals that are trained to survive in the cold, instead of bottlenose dolphins.
It might be because of the time a beluga was spotted near Norway that it was suspected to be a Russian spy. When it was first found, it had a harness around its body with the words Equipment St. Petersburg engraved on it.
The dolphins are at the harbor, but it is not clear what they are doing. They are being deployed as a defense measure.
According to UNSI, the harbor is out of range of Ukrainian missiles, but it could still be invaded.

There are specific whistle names for bottlenose dolphins.
