The Soviet Union was also very interested in harnessing animals for warfare. The killer animal in this instance? War dolphins. The project, developed in the 1960s, aimed to train dolphins to search for submerged warheads or other items, according to the Sevastopol State Oceanarium, Live Science previously reported. But Russia isn't the only country training dolphins for war; the United States has its own dolphin-training program, though the adorable marine mammals are not trained to carry weapons or kill people, because they'd have trouble distinguishing between enemies and friendly soldiers, according to the website for the U.S. program.
