True war story?

       I don't believe that "Three kings"  was a true war story. What made this a false war story was how the 3 soldiers survived in the desert for so long without and food, water, or places to sleep at night. The soldiers snuck out of their campus to abort their missions from the U.S military to search for gold. Also how the 3 soldiers did all that fighting, searching, and almost giving up their own lives just to leave empty handed. I feel as though soldiers who actually fight in those wars go to handle business and not get into any extra curricular activities like trying to steal gold.
