It is, a few years back I had the chance of shooting at a drone...about the same size as a trainer 40, nice plane....I was impressed that it could fly in such strong winds that we had.
Well....I got to shoot along with a load of Paratroopers...using GPMGs (M60 equivalent) and it was AWESOME
the hardest bit was getting that first shot in before everyone else started shooting...you can see the tracer...if you get the first few rounds in your brain and eye suddenly zero in.
Out of thousands of rounds we only bought down 2 I think.
Wonder how well we would have done with a 'Goalkeeper' like that fitted to warships...the radar controlled gatling.
