Second - and while this might apply more to "Generation Kill" - officer-less worlds or worlds with incompetent officers do exist. Again, I can't speak to EOD, so the lack of any commander may well be completely wrong. But as to the prevalence of dumb officers in the Recon Battalion of "GK"; well, sometimes that's just how the stars align. Occasionally you get a "peer group" of guys who barely passed Leadership 101 at the Basic School all showing up in your unit at the same time. In the air wing, this is mitigated somewhat by the fact that the numbers of officers are disproportionately higher than on the ground side, so a weak peer group might not cause the same damage. But to argue that it's impossible to have a group of incompetents all calling the shots at the same time is flat-out wrong. And while I haven't read the book version of GK yet, if that was the state of that particular Recon Battalion at the time, then it sucked to be them but it's entirely plausible.

And while running through the streets of Baghdad with only a sweatshirt and a pistol stretches credulity, he might have known just where to go even if he didn't know the neighborhood. As anyone who's been on a major base or FOB can tell you: just follow the lights. I'm pretty sure you can see them with the naked eye from space.
