But up until a few years ago every Marine, regardless of MOS, had to qualify once a year on a range at 100, 300 and 500 meters with iron sights. In basic we spent two weeks at the range. The first week spent training and "snapping in" or dry firing at targets. The second week was live fire, with qualification at the end of the week.

The Marines know what they're doing when it comes to weaponry, but to me not training troops on iron sights would be a major disadvantage if something ever happened to that expensive optic. Scopes are a big advantage when they work, but when they fail what do you have left?
