For the first part of the Redlight, Greenlight campaign mission in Call of Duty: Black Ops Cold War, you’ll be spending most of your time sneaking around a large base, trying to avoid detection. There comes a time when you and Woods are boxed into a corner, and the only way out is by going through it. When this happens, it’ll be on a firing range, and while you’re there shooting at the enemy, you want to fire at least 15 metal targets set up on the range.
The metal targets you want to hit are pictured below. They resemble exactly what you’d expect from a target, with a white background and a red center right on their chest. You don’t have to hit the targets right at the center, but you do have to hit them so they topple over, as shown in the image below.
There are a handful of targets in the streets, inside buildings, on the rooftops, and some of them are down for a few seconds before going back up. There’s plenty of enemies coming after you at this point in the mission, but feel free to run back and forth around the firing range to knock down all the targets you need to hit. The achievement will activate when you hit at least 15.
