It looks like the writer has watched a few documentaries on the SAS and then copy and pasted from some of Andy McNab's books, and still got it all wrong! I was surprised to see Miranda Raison in such a third rate effort, she should be able to do better. Some half decent acting from other members of the cast but unfortunately it couldn't compensate from the truly awful script and poor continuity. Anyone that has been to Wales knows not to expect bright sunshine in the morning during the winter, it's a rare enough occurrence in the summer! I had to watch it all the way through just to see if the end was as bad as the beginning, and I was not disappointed! More like Ultimate Force/Farce.
