Israel and Ukraine Show How Drone Smuggling Is Powerful New War Technique

Small, difficult to detect and able to pack a powerful punch, attack drones have become a formidable weapon in modern warfare. But when launched from deep inside enemy territory — as in Iran and in Russia this month — their impact is all the more devastating.

The surprise factor of having to fend off drones attacking from within combines a classic military strategy with modern technology. Spy craft and covert operations have long been a part of combat, but using them to build or deploy deadly drones behind enemy lines is a new tactic in the ever-evolving art of war, officials and weapons experts said.

That was the case two weeks ago, when more than 40 Russian war planes were hit by a swarm of 117 drones that Ukraine had secretly planted near military bases in Russia months earlier. Some were thousands of miles from Ukraine.

It was also the case in Iran, which lost missiles, interceptors and air defense systems that were destroyed on Friday by drones and other weapons that Israeli intelligence operatives had smuggled in earlier.

Many of the details about the secretive operations, and how they were carried out, remain murky to protect methods of intelligence collection and sources of covert information.

But Israel’s approach gave it an edge in its wide-ranging attack against Iran “because it’s coming from left flank,” said Assaf Orion, a retired Israeli brigadier general and defense strategist at the Washington Institute for Near East Policy.
