BBC2 are screening the second episode of this intriguing series on Monday 16th April 21:00 BST, with this episode including the close combat techniques of Fairbairn & Sykes.
Having only seen extracts of the CQC training, personally I need to see more before making comments, but there are errors already visible.
For an appreciation of what was taught and how, don't forget "NO QUEENSBURY RULES" covers the two years that Fairbairn and Sykes spent at Lochailort teaching not just SOE operatives, but soldiers from many regiments and nations.
If you're in the UK, BBC iplayer has the first episode online, and there are teasers and information as well, which can be found here:
An ambitious and brave attempt by WallToWall Productions.
