I agree. Unedited, grunting, bleeding videos are hard to watch, but war should make us very uncomfortable. A carefully cut network piece or hooting strafing run set to Kill The Lights has the gloss of truth, via the moving-picture format our eyes like to trust, but they're reductive at best. The first person view doesn't close the gap completely but it does get us closer.
Speaking of queasy, he linked to a singularly horrifying example: an unbroken 30 minutes of first-person video in which an ANA soldier trips a mine and his American patrolmates fight to triage him. Very hard to watch, graphic as heck, no-click zone for the fainthearted.
