When a disillusioned Army scout is teamed with an overbearing sergeant to locate a Taliban stronghold, they find themselves caught behind enemy lines, dependent on each other for survival. (War)

First observation is the use of the obvious – if they’re alone behind enemy lines they would be dependent on each other.
juxtaposing disillusioned with overbearing doesn’t really click.
Beyond that I can’t think of any way to give this a “hook”.
