Yes loads of good stuff there isn't there, like you say latrine admin, how to collect snow for melting etc. etc. and good to see so much detail on the improvised shelters. Only just got that doc this evening but will be reading it closely.
I'd already been inspired by some swedish bivi techniques, they used a vinyl diamond-shaped tarp/poncho ('Regnskydd Vävplast') like the norwegians which can be used individually (an 'emsamma vargen' =lone wolf, shelter) or buttoned together in many ways to make squad shelters ('knäppetält' =snap tents) with up to 10 pieces. I picked up a couple and plan to use them for Grays 'cold weather bivi' at Ribblehead the weekend before we go to Sweden.
