It’s hard being the middle sibling of a robot family. Large drones like the Predator and Reaper catch headlines and combat deployments as they launch strikes abroad. Small drones, like the RQ-11 Raven, come with troops into battle, hand-tossed to look over the next hill. The RQ-7 Shadow, and its slightly larger Shadow M2 sibling, is instead an in-between tool. Used as an advanced scout for brigades, it supports a group already bristling with firepower, so in American military service there’s been no real push to arm them.
