The video was posted on YouTube about five years ago, and it is most likely from a video game.
"Let me tell you [pause] about Russia," Moussa said in introducing the footage. "Russia does not play around. America was just playing, it wasn't trying to hit Daesh [the Islamic State]. If anything, they were patting Daesh on the back, funding and arming them.
"The Russians did it. Yes, this is the Russian army, this is Russian weaponry, this is [Vladimir] Putin. Yes, they are countering terrorism, truly countering it. Now you will see a terrifying video, terrifying."
Terrifying indeed — but not for the reasons Moussa thought.
According to the website Egyptian Streets, the footage is from the video game Apache Air Assault, which was developed by Russia's Gaijin Entertainment and released in 2010.
Moussa seemed to think that the footage was clear proof of the Russian military's superiority over its U.S. counterparts.
"Did you all see the precision?" he asked. "These are terrorists and militias and tanks, as you can see. These are Daesh fighters, and they have some weapons. And see there's this car, but in moments — gone."
Online, Moussa's blunder became a meme:
Moussa has had his share of trouble with the truth in the past.
But it is just one of several instances in which legal action was taken against him over similar accusations.
