Been there, done that, got the frostbite. As a young Cfn with 1PARA I was dicked for Baggage party on EX CALTROP FORCE held in California, the route was Lineham - Keflavik - Goose Bay - Some midwest shithole - Fort Ord, IIRC. Wasn't even allowed to suspend a hammock in the tail, as a lowly hat crow. I think the only thing that kept me from losing my tootsies was was the trial Combat Assault Boot goretex sock/booty/ slipper things, and the the newly issued goretex bivvy bag. The R&R was excellent though.Off track, sorry. I once spent around 38 hours in the back of a Herc, added another NBC state "NBC Freezing my fecking tits off", every piece of clothing I had, Noddy Suit, '58 pattern gonk bag and still cold, the Aircrew had heated suits, I don't think I stopped vibrating for weeks!.
