This is the helmet that appears to be worn in the photo, and that goes for $1400 apiece according to the article. I would also assume that helmet is being worn to make use night vision goggles, which are at least several thousand dollars apiece.

I mean, it could be possible that this is just some weird Azov chud trying his hardest to look like US special ops, but I kind of doubt it, and it would make perfect sense that US Special Forces are on the ground in Ukraine training groups like Azov and providing them with weapons.
