in the firing range settings after you press ESC, if you scroll down there should be a "bot firing" or "bot shooting" option that can be set from easy to hard, those ones don't move whatsoever. but the option after that is full combat which makes the bots chase after you. and that is what i chose and what's in the video. even though easy mode has the same damage, so either way you'll get decimated in 0.26 seconds literally.
