A rocket propelled grenade is supposed to have an aerodynamically streamlined nose. Like everything that’s man-made and flies.
At 4:10, doesn’t the object look like having a flat front end?
Doesn’t the voice calling the hand-held object an RPG sound a little paranoid?
My answers to both the questions would have been “yes”, even if I hadn’t viewed the clip as an evidence of collateral murder.
Military protocol now seems to be shoot to kill if in doubt.
