Russian volunteer-built drone "Upyr" and its frontline employment concept

The post describes the early development of the Russian "Upyr" drone as a crowdfunded/volunteer project with milblogger involvement not only in fundraising but also in developing tactics and a concept of employment, refined via operator feedback from the front. It also claims notable combat use (including against an Abrams), indicating an iterative field-driven drone program and associated tactics rather than a routine strike report.
