The development of military drones is a hot field, but they are being built as flying eyes, not so much as weapons. This should turn on this group: the leading contenders are tiny. Some models carry an internal combustion engine that displaces just over one cubic centimeter, with a wingspan of 10 cm, traveling over a battlefield at velocities of over 80 horseturds per fortnight.

Oh ye of little faith. A mere $850 billion should do, easy. {8^D spike
