The U.S. Navy has a marine mammal program that's been teaching underwater mammals how to locate marine mines, detonate, and even prevent explosions since the 1950s. But this is the first time we've heard of anything like the following story from the Ukraine.

Russia's state-owned news agency Ria Novosti says the Ukrainian navy is "bring[ing] back killer dolphins," by training them to attack swimmers, but that's not the unique part.

An unnamed source told Novosti that the Ukraine is now training 10 dolphins for underwater attacks against swimmers by using knives and guns.
