Dolphins have been trained to be used in wars. Dolphins are known widely as adorable, intelligent animals. What is not as widely known is that these crafty creatures were used by the U.S. and Soviet Union during the Vietnam War and the Cold War. Both countries studied the creatures for their sonar capabilities, but also trained them to detect mines, bring equipment to divers, find lost equipment, and guard submarines amongst other nifty tricks. #EverythingsInfo
