Still waiting for someone to realise that cheap quadcopters plus explosives equals ultimate suicide bomberoffensive assault vehicle.

Take the boku haram problem for a start. They already use drones to spot their camps and monitor their movements. Just one little step further is to add an explosives charge to the copter fly it right into the camp as closeto a soldier as possible and away from hostages then boom.

Next tech advancement is not to waste a whole copter to take out a small number. Equip the copter with chargers or grenades. Fly above the camp. Drop the bombs. Move copter out of sight. Rearm. Send it back. Continue until they surrender.

Escalation. No army moves without anti mini aircraft detect and destroy units. The units are a small Iron Shield varient. Spot flying hostile craft sound an alert take them down. This will not stop suicide bomber copter tactics unless defence mechanisms can blow them up.

Only a matter of time.
