The rules of engagement just changed. For decades, NATO doctrine was built on the supremacy of heavy armor, centralized command, and the assumption that concealment was possible in the "fog of war." However, during the Hedgehog 2025 exercises in Estonia, that fog was burned away by a handful of Ukrainian drone operators. A recent Wall Street Journal report by Jillian Kay Melchior highlights a jarring reality: a small team of 10 soldiers from the 412th "Nemesis" Brigade and the 427th "Rarog" Brigade effectively dismantled a NATO battle group of several thousand troops in just half a day.
