I ran AWT in Norway several times.
It was pretty standard and covered most of the things in the CF syllabus, except we did everything on skis. We also were pretty 'stripped down' kit wise and travelled with light 4 man tents, or tarps that we used for 4-8 man shelters. With a decent sleeping bag and a 2 man stove per pair, we did fine down to -30C or so - as long as we weren't shy!
This meant that we could cover long distances at high speed, which was good for practising the ol' 'Motti' tactics (below), which was our intended war role as light infantry should the commies roll across the border. We had to rely on the skills learned during AWT to stay warm though. This was perfect for the 'survival' night at the end, as we would issue orders for a raid at the start of the training period, with all the AWT fitting into BP for the operation, and strike like 'shivering starving lightning' on the op. This made it all far more realistic, of course, and also provided an opportunity to teach BP in a winter warfare environment.
So, I'd suggest that you issue orders for a 'Motti inspired' raid at the start of the training, deliver the AWT stuff within the context of BP for a raid, ditch the mega-heavy tents and snowshoes on the op itself in favour of hootchies/ improvised shelters and skis (but use them at the 'patrol base' during the training to get people familiar with them), and just generally treat it all like another offensive patrolling ex. I've found that when you exclusively focus on the survival stuff without placing it in the correct military context, it all degenerates into a boy scout - type winter camping jamboree (no offense to you scouts out there, of course) with no real tactical value. The troops respond in kind, unfortunately.
I think that our CTS clothing & equipment is perfect for this type of activity, by the way. The stuff we used in Norway was literally cotton and leather and we made it work, but it was effing uncomfortable!
Motti Tactics:
"Makeshift weaponry was not the only development to augment the Finnish soldier's lack of resources and manpower. The army also developed new tactics with time. One of the most popular was the motti tactics. In Finnish, a motti is a pile of wood with stakes holding it in place, which will eventually be cut up for firewood. The motti tactics was to approach and pin a Soviet column that adequate information has been gathered about. Then with a focus on concentration of firepower, the column would be attacked and divided into many isolated parts. The key was not to make the isolated part too large to put up a struggle which it can use to break out of the motti, or defend until Red Army reinforcements arrived. Then the mottis could be dealt with, beginning at the weakest, and cold, hunger and lack of supplies could weaken the stronger ones. This tactic was used to supplement the lack of ammunition, artillery and manpower the Finns had." http://ww2db.com/battle_spec.php?battle_id=30
