"As a slight aside, I'm sure the tacsims the military use _don't_ look or play like C&C, unless the 'tank rush' is now an accepted military strategy..."
What do you think, what strategy was used in the invasion of Iraq? They sent the tanks in, with support units going after them several days later, because they wanted a suprise attack and to occupy the country before the defenders realized there was a war. This was why there were no bombings before the attack. It turned out to be a good strategy, especially that there were no real defenders at all. The problem with a tank rush is that you supposed to raze the buildings and kill the civilians at the end because you are not equipped for long term occupation. (yes, the first computer based war sim was installed in the pentagon, so gamers took them up later)
About the xbox controller: I've seen the photo several weeks ago on a news site with the xbox controller hanging from one soldier's backpack during a training. It's a cheap way to get trained soldiers. That's why the us army used tracktor controls on most of its tanks, so soldiers who came from the country could drive them without training. Nowdays, most people who enlist have played halo on the xbox...
And yes, there was a remote hunting website with the ability to kill something from your keyboard and now the us south border can be watched by anyone via webcams. And the predator operators don't really leave las vegas... It is possible to enlist citizen soldiers (national guardsmen) for remote duty as robot operators so they get to do their civilian jobs too.
