So... "These games aren't as real as real life," is basically what we're getting here. It's really an answer to a question no one earnestly asked. Does anyone out there besides the biggest idiot think these games are meant to serve as a tutorial of some sort?
I do think it telling what he claims to have noticed about "those guys" on the battlefield. I'd be interested in some more numbers and data in that regard, but it's a plausible claim nonetheless. Video games certainly could lead to an overinflated sense of accomplishment (like guys who think they're badass for having a high score on Pac-Man or something)... and when the game, at least in some way, imitates a real-life activity, I definitely think some guys can start to think they really do know what's going on in those situations.
This could potentially lead to a lack of care and attention when they find themselves in that situation. If you
believe yourself to be knowledgeable, you're less likely to stop and think at moments where stopping and thinking could be critical. In
actual combat, this could kill more than just you, since the battle isn't a single-player campaign where the other guys are expendable NPCs...
But again, this is just his claim. It could be one of those, "I could see this happening" that sort of bleeds into a vague sense of, "I think I've seen this happen a whole lot, and I bet all those new, young guys getting hurt were into gaming." It'd be a worthwhile study, so that the military could adapt its tactics to breaking some of those FPS-instructed habits.
