Amazes me that Mars Rovers have been working since 1997 with vast improvement at each new implementation by JPL and yet we see such comments,
Recently a Hungarian Univ. group working on a shoestring budget developed from cheap off the shelf components autonomous small drone swarm behavior. There’s a youtube video of it. Once that sort of work is done along with power source, platform, sensor, and weapons package add-ons are easy. And it’s scalable from mosquito size on up. I suspect that proven results are sufficiently advanced that red team are or have begun working on defensive measures and doctrine.
Now, about that Zika outbreak....mosquitos, really?
Another mission profile that has been mentioned to me, already existing everything:
A bird-sized and bird-appearing drone that is launched to sit in a tree or on a roof across the street from the target’s address.
It just sits there looking all day at the driveway and porch and doors, looking for its target face. While it waits, it recharges with it’s little solar wings.
It can wait for months. When it sees its target face, it lifts off, swoops in, and explodes a grenade in it’s face.
BTTT ...... tick..... tick.....
