In MW4 DMZ, in order to complete the Eye in the Sky mission, you need to successfully claim five airplane supply drops. You will be able to achieve this goal by capturing SAM sites and destroying cargo helicopters, as well as collecting the dropped supplies from those helicopters. You can also look for other airplane supply crates located around the map to complete this mission.
Eye in the Sky Mission Objectives
There are three main objectives under the Eye in the Sky mission in MW4 DMZ. Namely, you need to capture a SAM site, shoot down the Chopper that appears, then collect the loot from said chopper. It might seem easy on paper, but you need to be prepared to face the wave of enemies guarding the SAM site as well as the felled chopper.
Capture a SAM Site


Locate a SAM site on the map and kill the guards present there. After securing the location, interact with the control panel to capture the SAM site. After capturing it, you can continue playing while waiting for supply drops to appear.
Open 5 Airplane Supply Drops

Once you take control of a SAM site, allow the site some time, like two or three minutes, and it will then target a transport helicopter flying above for cargo. The SAM site will fire missiles to hit the helicopter and bring it down. Once that has been done, the helicopter will drop a supply crate marked on the map with a blue icon. Go to the location and collect the supply crate.
You also have the option to search for other supply drops that may be available in other locations on the map. Continue opening supply drops until you have completed the objective. After opening five qualifying supply drops, go to the extraction point and leave the area to finish your run and complete the mission.
