I don't think you're taking this seriously enough. It is a clear contravention of Rule 42.
6. Dangerous and unfair shooting
(a) Shooting of fast short pitched bullets
(i) The Shooting of fast short pitched bullets is dangerous and unfair if the umpire at the bowler's end considers that by their repetition and taking into account their length, height and direction they are likely to inflict physical injury on the striker, irrespective of the protective equipment he may be wearing. The relative skill of the striker shall be taken into consideration.
So. Fair do's against the escort but a bit naughty against the players.
Clearly they needed to have exerted more care with their use of automatic weapons.
(ii) Any delivery which, after pitching, passes or would have passed over head height of the striker standing upright at the crease, although not threatening physical injury, shall be included with shooting under (i) both when the umpire is considering whether the shooting of fast short pitched bullets has become dangerous and unfair and after he has so decided. The umpire shall call and signal No Bullet for each such delivery.
I just hope that they take care when using mortars ...
(b) Shooting of high full pitched munitions
(i) Any delivery, other than a slow paced one, which passes or would have passed on the full above waist height of the striker standing upright at the crease is to be deemed dangerous and unfair, whether or not it is likely to inflict physical injury on the striker.
or grenades
(ii) A slow delivery which passes or would have passed on the full above shoulder height of the striker standing upright at the crease is to be deemed dangerous and unfair, whether or not it is likely to inflict physical injury on the striker.
