In the popular imagination, the dolphins are known to make an excellent sex, be very intelligent and have a very good figure of diaries and notebooks, while normally the association with the force is reserved to other sea creatures like turtles, frogs and sharks.

In San Diego and still operating, the US Navy Marine Mammal Program has about 70 dolphins from the war, and is the only other contingent of dolphins battle in the world, as well as the newly acquired from Russia in Crimea.
At the end of the Cold War, the war dolphins trained by the Soviet Union in the Crimea had passed under the control of Ukraine, but without major geopolitical reasons to be paranoid did not fight much.
According to the BBC, more than 10 years ago, could not afford to feed them, Ukraine has sold many of his dolphins to Iran along with some sea lions and some walruses.
"In the Ukrainian Navy they lack the funds to manage these technologies, and some projects have been canceled,".
Vladislav Seleznyov, the Ukrainian army spokesman, told the Washington Post that even if the dolphins were trained to fight, do not actually have to be used for that purpose.
Also during World War II, the United States used the bats as bombs against Japan.
We hope that those poor dolphins are not used for the war.
