These quadcopters and fpv drones proved themselves as powerful tools. At Eastern regions they are much more effective and caused much more havoc than TB-2
But I think we should get some lessons from that. These are extremely dangerous weapons especially soldiers without anti drone systems especially for our soldiers fighting in the mountains.
i've been of the opinion for some time that armed drones should also being getting smaller and smaller. The drive to create bigger and better drones is important, but in airspace that is contested smaller drones have more utility.
