There's no way that Frye and Darrow are officers
...not to mention captains!
Officers are usually calm, calculating and pragmatic soldiers. Leaders who see the big picture. As opposed to how Frye and Darrow were portrayed as impulsive, volotile and emotional.
I get that the movie needed them to create controversy, but atleast make it realistic. No way those two douchebags would have made rank that high. They'd be seargents at best.
