1: little to no experience with combat, will have no idea how to even use logistical equipment.

Do you have anything sources to back you up there? The ski patrol started from the 10th Mountain Division. They also have a good idea of how logistics work. They can move people/supplies through the use of snowmobiles, Snow Cats, helicopters, etc. They have a number of ways to communicate. Not only that, but they know the terrain extremely well. They have to... Otherwise, they could get crushed by an avalanche, lost in the freezing cold, etc.

2:Massively outnumbered by over 2 million service men.

So you are going to try the Russian strategy? They cannot attack unless they can get in the mountains which would become difficult if roads were demolished or avalanches/rockslides covered the road. Those two million cannot get in by helicopter/air transportation alone without it taking a long while. Even then, they do not know the terrain as well as the ski patrol does, nor have any of our soldiers in the Middle East really received winter training. In addition, they are at a high altitude which may make it difficult for those soldiers that are not accustomed to it. This can whittle the numbers down already/impair the strength in numbers argument.

3: literally a single jet could solo

I am not sure there is a correct way to argue for or against this. Literally the Rocky Mountains are massive. A single jet does not have the firepower or amount of fuel to be able to attack multiple locations within this massive mountain range. It needs to refuel and rearm. Not only that but it is highly likely that, despite all of the advanced technology that a jet has, it will still miss it's target or that it doesn't even know what it's target is besides ski lifts.

4: the days of using a mountain range as cover vs a modern military is over

Do you also have factual evidence to back up that claim? Mountains can provide cover against things such as carpet bombing. In addition, since it is happening during the winter, if a massive blizzard came in that could impair the military's ability to fight, especially if it was a white-out (where you can't see anything past your hand). It would force the military to wait out the snowstorm, especially if it is in high elevation. Again, the majority of the 2 million service men have not had extreme winter/mountain training so they cannot be as prepared for this.
