Back to the subject, 
I still do not see how so many people can be a part of a conspiracy. I have read through the old posts and I keep reading that it would not take very many people to make the conspiracy. I have seen calculations that have put the number below 100 and I have seen others that put the amount in the high thousands or millions. There is not evidence of anyone working for the conspiracy, and in fact, the flat earthers will tell you that the fact that there is no proof is actually proof of the conspiracy.
It would take millions of conspirators to make this theory happen.
Back in my thread my argument to tom bishop(which he ran away from, or ignored)
i said that if the conspiracy WAS real there would have to be millions in on it. and to be honest...that many people keeping their mouths shut? ya thats kind of impossible for humans, no matter how many threats you give them
Thats why the government branches don't share secrets with each other, the less people know the better, and even with little people knowing things, stuff still gets out...but millions?! ya.. 
I spent many years in the military. I am not saying that the military is very efficient; however, I am saying that a study of the military will tell you that the number of conspirators would be much, much greater than it is claimed to be.
The ice wall ninjas need to eat. I do not think anyone would argue with that. Sure, some can say that they eat MREs that civilians think went to soldiers. But, I can assure you that it would not take long for these pre-made meals to make you sick. If I was an ice wall ninja, I would require fresh food occasionally. Actually, I think the real term I would use is frequently.
So, the ice wall ninjas would need cooks. The cooks need an ever steady supply off food, so there must be many pilots who ruetinely fly to ice wall in order to feed them.
And, their food source is not the only thing that makes this theory suspicious. The ice wall ninjas, no matter much they are paid, would need time off to spend their money. So, there would have to be replacement ninjas in order for them to have days off.
Also, the snow mobile would need fuel. I have yet to see a claim that the ice wall ninjas drill for and refine their own fuel. Therefore, there must be a steady stream of ships, with sailors aboard, feeding their vehicles.
Next, people get hurt. Even ninjas will succumb to the weather on occasions. There would need to be medical staff standing by to treat, even the occasional, case of frost bite.
As a former military person, I would say that the smallest amount of support personnel compared to the actual guards would be 10:1. In the real military, it is more like 100:1.
