In a few early June days, underlying assumptions about Ukraine and Russia were shaken in three ways. On June 1st Ukraine launched one of the most daring raids in the modern history of warfare, releasing killer drones from trucks to scavenge on strategic bombers deep inside Russia,

Ukraine said its “Operation Spiderweb” attacked Russian warplanes worth hundreds of millions of dollars, utilizing drones that each cost under $1,000 and were launched from wooden containers carried on trucks.

Drones are “ubiquitous, because they are quite useful, and they're demonstrating that every day in Ukraine,” one analyst told NBC News.
