The Mark 6 Mod 1 MMS (Marine Mammal System) is a dolphin trained to find and tag enemy swimmers. When the dolphin locates an intruder, it comes back to its handler’s boat and rings a bell. The trainer places a conical marker buoy over the dolphin's snout which the dolphin uses to ‘tag’ the swimmer: the buoy floats to the surface, flashing a strobe light to mark the location for security team.
