Will they be controlled by a collective overmind?

I'm still not sure if this is some kind of joke. I don't suppose that trying to engineer a battalion of cyber-insects is entirely out of the question.

The article has some anecdotes of past attempts at animal-based warfare:

WWII: Attach a bomb to a cat and drop it from a dive-bomber on to Nazi ships. The cat, hating water, will "wrangle" itself on to enemy ship's deck. In tests cats became unconscious in mid-air

It looks like the U.S. military's Tierekrieg strategies have a poor track record.

EDIT: Predictably, there's some great commentary over at Pharyngula.
