My son went to war… and the weapon he carried was a camera.

Even though he wasn’t armed and fighting while in northeastern Afghanistan, as a journalist embedded with U.S. troops, Carlos witnessed the deadly horrors of battle while under fire in one of the country’s most dangerous and hostile valleys.

My son went to war, but I know I’m lucky. He came home.

The riveting documentary of his experience, The Hornet’s Nest, offers a soldier’s-eye view of what it’s really like to wonder, from second to second, if you’re going to die in a remote part of the world far removed from those you love. This is not a scripted movie… this is the real deal with heart-breaking consequences.

When my son announced he was going to Afghanistan with his father (my former husband), I knew I couldn’t stop him. I was his age when I left a comfortable job as a CNN producer in Washington, D.C. to cover the wars in Central America in the 1980s. I guess, in a sense, Carlos joined the family business.

Knowing that Carlos shot the movie’s captivating shaky-cam video while bullets whistled above his head is gut wrenching. I watched the film with him beside me. Some of the families of the soldiers featured in the movie will never be able to do this.

The movie is not all bang-bang. There’s a terrific scene with members of an all-female Medevac team, who risk their lives helping extract wounded soldiers from the battlefield. The story of these women alone is incredibly compelling.

But the movie never lets you forget you are in the middle of hell.

What is it about people who run head-on into dangerous places like war zones? Believers in a cause? Adrenaline junkies? Journalists? Fools? I’m not just talking about people like my son (and me, if I’m playing fair). There are plenty of soldiers you hear from in the movie who go back for a third and fourth deployment… some of whom die doing what they love, leaving sorrow in their wake.

A moving memorial service for six fallen soldiers is, perhaps, the toughest part of the movie. Their surviving colleagues decorate makeshift altars with the only things they can offer… a can of Coca-Cola, a personal name-patch ripped from their uniform, a photograph. A tribute to a friendship forever lost.

The Obama administration announced last week that U.S. involvement in Afghanistan, the longest war in American history, will be completely ended no later than 2016.

This haunting movie doesn’t offer any judgment about the war or America’s role in it. Only the ugly reality of combat in real time.

Like I said… I was lucky.

My oldest son came home.

This time.
