Collecting one of them is required to complete the DMZ order "Payment Due," which is in the second stage of the "Human Intel" chapter, but completing this requires you to know what to look for in order to find a dynamic op phone. We're here to help though, so here's a complete explainer on how to find and collect a dynamic op phone in DMZ in Modern Warfare 4. How to collect a dynamic op phone in DMZ Graphic: Ford James/Polygon Source images: Infinity Ward/Activision via Polygon When you've deployed into a match in DMZ, open your map. Scattered across the entirety of Hajin, you'll see small, green icons that look like phones or handheld radios. If you zoom in, they'll have smaller icons within the green part, which tells you exactly what the dynamic operation is. All you need to do to collect a dynamic op phone is make your way to one of these icons and interact with it. That will begin the dynamic operation, which you'll then need to earn 11,500 Cash from to complete the next objective. Dynamic op phone locations change every round, but there are so many of them on the map, you're unlikely to ever be too far away.
