Shoot from the Hip

Complete Glassed without any player using Smart-Link (the aim-down-sights zoom) - hip-fire only, the whole mission. Just never press the zoom/ADS button. Note the check covers all players, so in co-op everyone must abstain - solo is far safer. Do it on a low difficulty so hip-firing isn't punishing, and pair it with Going the Distance (no vehicle) on the same run.
