Really? I didn't think anything there was so implausable that it damaged my sense of immersion, aside maybe from people acting like idiots. I mean, I didn't even think the camera was unnaturally durable, or had hideously long battery life. I mean, when you think about it, the entire movie takes about 6 hours, and the camera isn't even on the whole time, it's filmed in short bursts. The only times it really suffers severe punishment are when it drops out of the chopper, and lands on wet grass, and after the bombing, which I suppose is fairly odd, but it's perfectly believable that the camera was broken at that point, but the storage media survived.
