County of Essex
This is a story that comes from the Express, which is even worse than the Mail.It all does seem rather dubious, and try as I might I can find no reliable source for it.
The original story was so incredible it was just laughed at. (He was 27 with 15 years experience) so not even remotely edited/fact checked. The SAS doesn't talk about operations so shit tabloids can make any shit up on a slow news day.
