The recently retired OH-58 Kiowa Warrior doesn’t look like much. It’s small, quiet, and, technically, it’s a reconnaissance helicopter. From a distance, it could be confused for a local news chopper or a toy helicopter in “Honey, I Shrunk the Kids.” But to many of those who’ve served on the line in Iraq or Afghanistan over the years, the Kiowa looks like something else: a bad day for the enemy.
