Timothy Bertram spent more than a decade in the US Marine Corps, while his son, David, just finished up a six-year stint, which included two combat tours in Iraq. Both are avid gamers, playing everything from real-time strategy games to first-person shooters. They are currently playing Operation Flashpoint: Dragon Rising—which Timothy claims is the most realistic FPS he has ever played—and both have the prestige edition of Modern Warfare 2 on pre-order. So what does Timothy think about the leaked video?

"In the real world is this [terrorists killing civilians] far fetched?" he explained, "No, not at all."

"The question is," he continued, "just because that is the way it is, do we need that in a video game? I don’t think so. In my opinion it dumbs down the absolute horror and viciousness of these tactics, and glorifies the acts. I personally have played some of GTA, but abandoned it after continually being forced to shoot police officers."
