Video clip of military helicopter crash is from a video game, not the war in Ukraine
This isn't a real video showing the Ukrainian military shooting down Russian helicopters. It's a simulation from the Arma 3 video game.
Using keyword searches we found the same video on YouTube, which described the scene as a simulation from Arma 3, a military tactical shooter video game that's been used several times in false claims about the fighting in Ukraine.
The same Facebook account posted another video titled "Rus_sian Helicopter Convoy firing at U_kraine Military Base." It, too, is from the same game and doesn't depict real-life combat.
We rate these posts False.
UPDATE, June 7, 2022: We updated this fact-check to include another Facebook video misrepresenting video game footage.
