This typical covert censorship in war movies is so conventional and prevalent by now, that there's an actual office in existence called the US Army Entertainment Industry Liaison. Indeed, authenticity when it comes to locations and props, has its price.
A very familiar Stateside war drama -- narratively, the film just goads when it's convenient and shrinks when it suits its purposes, never feeling like an honest exploration of its characters' problems.
So is there a middle ground between supporting the troops but not condoning them? The military certainly hopes not. Which makes the film, however compassionate, a bitter pill to swallow. Or as they prescribe for whatever ails destroyed vets - Take a pill.
