Reports of US "firing in the air" are interesting.
As a military historian of small merit, my understanding of British protocols is/ was that such a thing was not to be contemplated.
Transfer of control by civil power to senior army officer, mob ordered to disperse or we fire, mob fails to disperse, officer orders nominated soldiers to kill nominated targets.
Is this no longer doctrine?
Firing in the air teaches the mob that bangs kill nobody.
I wonder where our 600 Paras are ......... no mention anywhere that I have seen.
