There are several ways to unlock Call of Duty: Modern Warfare 3 operators, though only a handful will be available initially. You won't be completely without choice if you played Modern Warfare 2, however, as you'll have access to any operators you acquired while playing it.
Modern Warfare 3 is adding 25 operators into the mix so you'll have plenty to choose from once you gain access to them—perhaps collecting them will help take your mind off the eye-watering 200GB needed to install the game. With that in mind, here I'll list every Modern Warfare 3 operator, as well as how to unlock them.
