A_b_i_w, it looks just like the old, pre-cab tractors of my youth still used in that part of the world. Look carefully and you can see the steering wheel, mirror and the hot rear transmission casing. No AAA system I've ever seen looked like that, nor would it be stuck out in the open in that way with a hot barrel after being used.
Sorry, but convince me it's anything more than gung-ho bullies murdering some farm workers. I'm happy to be persuaded otherwise.......
No evidence of secondary explosions which would be expected if this really was a AAA site and crew.
