Bunker artwork drawn by troops in the Iran War often includes tallies of drone attacks and counts of hours spent in the confines of concrete shelters.

For thousands of American troops across the Middle East, the Iran War has been defined by the wavering siren just before a drone or missile attack, the dash to a bunker, and the monotony of waiting until it’s safe to emerge, sometimes hours later.

And when troops hunker down — whether in a concrete shelter or porta-potty — they often chronicle their trials and tedium through graffiti. Now, photos of the new war art are starting to emerge.
