This one's too cool.
The US military engineers are on the verge of developing Spy Robots. Like the Bond franchise, SPY KIDS etc etc. We have seen them in many many movies and the time maybe that we see a real one this time.
It may be a micro sized, fully functional tiny little insect. Just that it won't suck our blood :P
It could spy on enemies, record their conversations, give live feeds about ongoing situations and so much more.
The possibilities that this insect can do can be limitless.
I don't think there is a need to explicitly put an image of an insect.
