No doubt an invaluable document for the producers of "The Hurt Locker" and HBO's "Generation Kill"... One of this new film's strengths is precisely this ability to evoke, with great tact and subtlety, a wider historical perspective, to recognise that while the technologies and training have improved in the intervening period, the resources made available to the average soldier, and the pressures exerted upon him, remain very much unaltered. Worse still, in such a brute-force, macho environment, is how aftercare is sorely, and in several cases *fatally*, lacking - a cursory passing-out of surveys that brings the world no closer to knowing or treating post-traumatic stress disorders. Once you've been told - by your superiors, and your own frazzled mind - you are surplus to requirements, what do you do with that murderous rage that's been installed inside you, other than turn it back upon yourself. It's a tough watch, but - funded by various veterans' groups - one that has the soldiers' very best interests at heart. At 70 minutes, it's brisk enough not to induce compassion or combat fatigue, yet its most indelible images - whether dead bodies in the road, or returning soldiers embracing their loved ones - stay with you far longer than that.
