> For protection against enemy divers, dolphins will swim up to the infiltrator, bump into them and place a buoy device on their back or a limb using their mouth. The buoy then drags the outed diver to the surface for easy capture. When trained sea lions perform the same maneuver, they use a kind of handcuff with their mouths to attach the buoy
Imagine if we did this on land: monkeys or dogs handcuffing or tasing people! Surely they wouldn't be deployed against civilians and I know there have been exotic animals travelling with military (like bears) but training animals to fight humans with TOOLS looks incredibly hard.
