Professor and former State Department Counselor Eliot A. Cohen, writing about the elite British Special Air Service in his 1978 book “Commandos and Politicians,” noted that:
The SAS fought in Malaya, Borneo, Muscat and Oman, largely as a counter-insurgency force but also as jacks of all trade ready for various delicate and dangerous tasks. The British government kept their activities secret, hoping to use them as a discreet, non-publicized intervention force. Ironically, the curtain of secrecy surrounding the SAS made it an intriguing topic for speculation. Its reputation grew in inverse proportion to what was known about it, to the point that the government could use it effectively as a symbol because of the mystery surrounding it.
While today there is a great deal more information available about such elite formations – particularly due to the rapidity with which information is gathered and disseminated in the information age and their place in popular culture due to films and video games – there still remains a great deal of mystery and secrecy surrounding such units. Some of this shroud is completely appropriate and understandable in order to provide legitimate operational security for such unit members and their missions, but others argue that this sometimes goes too far.

What makes me laugh out loud as i read this sort of stuff is that folks like the terse Mr Turse at The Nation think everyone in “SOF” is a “killa”.
When I commanded a TSOC Signal Detachment and launched a 2-man comm team to the Balkans or Africa, i “deployed SOF”. However it is fair to say that i didn’t put a lethal assassination team on the ground.
That’s why reports like Turse’s should be mocked as so much hysterical screaming.
