How many different types of UAV's do we have and why do we need so many different ones isn't it overkill?
No clue on how many we have, but the reason for having them is simple. The technology is in it's infancy, so the more test beds you have the quicker
you will progress. Since it is becoming more and more apparent that the American public frowns on soldiers getting killed, it makes sense to progress
to the point where using humans in combat should be an option, not a given.
