I carried a sleeping bag and/or a jungle hammock (to keep me off the ground) on training missions in the US,but on combat missions I just sat right down on the ground on my ass,and leaned back against my rucksack.
Didn't even carry a ground cloth.
If I couldn't eat it,drink it,or kill the enemy with it,I didn't carry it.
@sneakypete Ain't the same I know... But I understand that... The economy of it... My go-bag complete (in 3 season mode), with no water in the cans, is around 35 lbs. That's ruck, forage bag and belt w/o rifle considered. I do have 3 days food onboard, but I run tool heavy, intending to build and forage rather than rely on supply. That might be different from a soldier in that I have no supply lines to rely on.
Of course all that changes in the winter, but the go-bag stays the same - just strapped entirely intact to the top of a 50L pack to handle all the added food and loft (coats and sleeping bags) necessary to keep warm in the snow. All that is different anyway, because it's all on a polk dragging behind me. But once I make camp, the go-bag is what I take out on a scout.
I don't carry much for comfort. An alcohol stove and some teas and coffees, and that woobie... Though really only the teas and coffees are inarguable as comfort. the alcohol stove is a redundancy I would admit and the alcohol to go with it a burden. But it also can fire up a bush pot, and has on many occasions, when rain made building a fire a bother.
And the woobie I would have anyway, if only for its first function as a poncho liner. No doubt you know the cold fall rain in the mountains, and you must know what that blanket liner does in that condition. And since it is along, it is SO dang handy for so many things. Primary among them, as with the soldier, a lightweight blanket that wads up to nothing and is easy to access without having to unload your bedroll.
