I appreciate that Blain. However I am a firm believer in "borrowing" Ideas and learning from other similar scenarios or techniques. (For example the Finns have a great deal of experience with extreme cold operations in the Lapland area. at similar temps to the ones you mention) Of course there are other issues (altitude for example) which I can check with some HA mountaineers that I know. I am just throwing some ideas out there for discussion
Absolutely.
Here is a relevant document on Pakistan Army experiences in High Altitude warfare by Maj Asim Malik (Baloch).
