Hurr Durr Drones Syndrome
Hurr Durr Drones Syndrome or HDDS is a school of thought that tanks are obsolete because of drones. It was first identified by LazerPig, a YouTuber.
He points out that most inexpensive drones are incapable of carrying payloads that could destroy a tank. They also lack the range and communications equipment to deliver the explosives. Military-grade drones exist, but they are complex and expensive.
