Visible crew/equipment: Near the end of the movie when the convoy is heading back to the Pakistan Stadium, a Humvee stops briefly to allow a man to walk across the street with a child in his arms. When the shot changes and the Humvee begins driving again, a crew member or cameraman is seen inside the Humvee wearing a white shirt. All of the men who entered the Humvee were wearing fatigues.

Answer: The answer to this question is quite simple. Whenever any book is put on to the screen things must be glorified in order to catch the eye of a film goer. In movies like this one, heroes, brave men, and down right bad ass characters are what people need to see. If the movie was just like the book, there would be just a whole bunch of equally important characters, which is something very rarely seen in movies. So in short they made sgt Eversmann a main character simply because the movie needed one.
That makes sense but does anyone know why Eversmann was the specific soldier chosen as the focus for the movie?
