Resolves YES if there is an attack on US military airplanes parked on a US military base similar to Ukraine's drone attack on Russian strategic bombers before 2028.
The US military base doesn't have to be in the US. Any US military base in other countries (like for example Okinawa or Ramstein bases) count.
The drones have to be launched from foot or from a vehicle that's either a civilian vehicle (like the truck Ukraine used, but a civilian type boat or even an airplane like a Cessna would be ok).
The drones have to be launched from within 5km of their targets.
It doesn't matter for resolution of this question if the attack does any damage. However, the attack needs to be executed. A plot like this being foiled does not count. For the attack to be "executed" at least one drone must have launched from the delivery vehicle. The drones could even be ground vehicles or legged robots. As long as they are unmanned and carry weapons or explosives they count.
I won't be betting in this market, in case resolution becomes subjective.
1,000@ElliotDavies yes, someone walking up or driving to a place near the base and launching a drone with an explosive strapped to it at airplanes on the base would count.
