Last night we saw my brother off to a faraway post, where his (civilian) job is taking him for a few months. The international terminal was quiet; soldiers dressed in camouflage gear sat alone at the bar, flipped through magazines at the newsstand, called home one last time before boarding their flights.

We sat with Drew, chatted, had a beer. Before long it was time for him to pass through security and check into his flight. I waved until I couldn’t see him anymore; I watched as as he squared his shoulders and moved his tall frame toward the future.

I was struck by how alone Drew and all of the camo-clad seemed. Where they are going only they can go. What they are doing only they can do.

It’s a scene that plays out here every day of the week without fanfare, a scene I never think about but on which our easy lives are based. The timeless march of soldiers heading off to war.
