Doctor Linda Morales is a character featured in the Spec Ops story in Call of Duty: Modern Warfare.
Dr. Morales is a British physician in internal medicine. She is a volunteer physician in Verdansk for the World Humanitarian Project.
The first objective in Operation Paladin was for ARM-4 to find and extract Dr. Morales, who was captive at Storage Town. She provided intel about the storage of weapons, which she claimed was "for the weekend." This turned out to be a nuclear weapon.
Morales' intel led to ARM-4 finding more Al-Qatala nuclear weapons and stealing the core from one.
