Summary
Some experts contend that drones can revolutionize war by shifting the offense-defense military balance, reducing asymmetries in military power, and reducing the need for ground forces. A new theory challenges this view, showing that drones are vulnerable to air and ground attacks and require costly equipment and trained operators. They can also be thwarted by an adversary hiding its ground assets.
