Most people know about military working dogs, but there are some lesser known creatures that also conduct missions for the U.S. military:
First, they can be restricted to glass tubes at check points. When people, cars, and packages are moved through the checkpoint, handlers watch the bees to see if they start moving their proboscis, a feeding tube that is part of their mouth. Movement in multiple bees is a sure sign that explosives are in the area. Alternatively, the bees can be fitted with radio transponders and released into a large area. Handlers then watch on computer screens to see where the bees swarm to and then check that spot for a mine.
2. Dolphins and Sea Lions
One team of dolphins and handlers in the program, MK8, can deploy ahead of an amphibious landing group and indicate safe routes for ships, Marines, and other forces.
