Good film. First thing that tipped me off about that vehicle recovery method of burying a wheel to use as a fixed point to recover a vehicle. I remember being trained on a similar device that you threaded a towing cable through then pumped a handle. Can't remember what it's called.
Just been watching ICIA on ITV4. MSM was I believe the then rank of Mechanical Sergeant Major (RASC?). Did this rank subsequently become ASM? If so, when? Or did ASM (REME) exist alongside MSM. A great film if a tad overacted in some scenes.
