Invisible Threat

Call of Duty: Modern Warfare 3 Walkthrough and Guide by vhayste  

Invisible Threat

Use the UAV and Juggernaut Suit to find and defuse IEDs.

You can do this solo or with a partner. If you're doing it solo, you have to take note of the following:

- Dig in and move behind covers

- Mark IEDs with UAV, use predator missiles to take out multiple enemies

- IEDs will disappear from view from time to time so you have to mark them again with your UAV.

- Tank will appear near the bridge

- Enemy helicopter will appear near the end

If you're doing it with a partner, one of you will be the defuser and one will be the support sniper and UAV controller. There will be more enemies in this mode so the sniper will have a bigger responsibility in protecting his partner on the ground. You may refer to the video below to get an idea how it is basically done.
