To begin dynamic operations in Call of Duty: Modern Warfare 4's DMZ mode while in free roam, players need to find and collect a dynamic op phone. These phones are essential for completing the second stage of the 'Human Intel' chapter, specifically the 'Payment Due' order.
Locating Dynamic Op Phones
Once deployed into a DMZ match, players should open their in-game map. Dynamic op phones are represented by small, green icons resembling phones or handheld radios, scattered across the entire Hajin map. Zooming in on these icons reveals smaller symbols within the green area, indicating the type of dynamic operation available.
Initiating Dynamic Operations
To collect a dynamic op phone, players simply need to travel to one of the marked locations and interact with the device. This action initiates the dynamic operation. To progress the objective, players must then earn 11,500 Cash from the operation. The locations of these dynamic op phones change with each new round, but the map features a plentiful supply, ensuring players are rarely far from an available device.
