If this isn't a fake account, you have to figure that this sort of thing is an investment.

Come decades later when no one is paying attention to the intricacies of what's real and what's fake, something like this is very useful when you're the winner and you decide history anyway. It becomes part of a raw number when citing the gross sum of testimonies and it becomes such a fool's errand to dig deeply amidst so many other lies and juxtapositions of the truth that it doesn't even matter that this is Arma footage. The actual truth then ceases to matter, especially if you affix questioning the lie with serious social, financial, and legal consequences later on.

The lie eventually becomes the truth no matter how poorly crafted that lie was and at best you will look autistic for pointing it out later down the road if all goes well.
