"Close Air" 7th mission in Call of Duty: Modern Warfare II campaign- Walkthrough Gameplay
The first thing you have to do is confirm visual on the friendlies on the ground. Move your camera around until you find them; they will signal with a laser you can easily spot by turning on your thermal vision.
Your next move is to scan the area to find any target with arm guards. Use the zoom-in feature to better see what's going on in the ground.
Once the truck starts moving, track it to see if it has something fishy.
Next, turn your vision to the nearby greenhouse (you won't be able to see what's going on inside unless you turn off your thermal vision).
After checking the greenhouse, you will be clear to open fire. Still, you can only attack armed people, so be careful not to launch an attack on civilians or buildings.
When using the plane's weapon, you must consider the aircraft's distance from the ground and its movement. This means that the bullets will be delayed from when they are fired to when they hit the selected target.
