Last time I was involved in the similar part of the country for a similar reason, an erstwhile member of the Guards Division had tried to emplane by walking down a slope to the running Lynx at an OP in the dark, amazingly he walked into the blade tips on the CMRB blades with his Kevlar walking cap on, got knocked sideways and unconscious, was thrown in the back and flown to hospital. 3 days later he was as right as rain (for a Guardsman) and discharged, the Lynx just needed 4 new blades and a bit of RTB. If that had been the old steel blades he would have been decapitated.
