Can't lift a fairy cake with a gale on the nose.
They're in Afghanistan for the same reason that they're in Iraq.. Despite the fact that they can't lift a small fairy cake, at night, with a 25kt wind, the Army big wigs cannot stand to see a "JHC supported op" without sending the Teeny Weenies in. I suppose if one of the Chinooks goes down with some chips on a mag plug, the Lynx could always bring a new plug out!!!
