Indeed some of our own 'Rock Apes' that served in Aden can tell us that from 40 years ago!
As one of those Rockapes (it's nearer 50 years than 40
) I can confirm that there were well known cases of summary justice being meted out when individuals had been caught. The nearest the army came to what might be called group action was when "Mad Mitch" and his Argylls reoccupied Crater City, during which period a number of known terrorists were shot. But there is a world of difference between that and doing what the SS were famous for, ie summarily executing civilians as a reprisal for actions taken by others, which appears to what is being advocated by some on here.
I'm certain that neither the RAF Regiment, nor any other British military unit in Aden acted in that way, and I'm sure you're not advocating that sort of thing,
