Via Instapundit, I found this interesting story on the crossover between video games and military action:

But there's another reason, not often talked about, for the success of CROWS. The guys operating these systems grew up playing video games. They developed skills in operating systems (video games) very similar to the CROWS controls. This was important, because viewing the world around the vehicle via a vidcam is not as enlightening (although a lot safer) than having your head and chest exposed to the elements, and any firepower the enemy sends your way. But experienced video gamers are skilled at whipping that screen view around, and picking up any signs of danger.

So maybe all that time on things like "Call of Duty" aren't just entertainment - I can see my daughter's retort to get off the GameCube already: "But dad, I'm doing this for the good of the country!"
