The MAAWS appears in the campaign once, in Brave New World, where it is used to shoot down an Mi-24 Hind and an EC-635 assaulting the Liberty Wall. Unlike its multiplayer and Extinction counterpart, each fired rocket remains intact instead of splitting into two others.
Multiplayer
The MAAWS appears in multiplayer. When fired, the rocket splits into two other rockets and can lock onto enemy aircraft and aerial pointsreaks (as well as the user's killstreaks). There is a Laser Sight attached to the weapon, allowing the user to manually guide the rockets to a designated target. When aiming with this weapon, instead of using sights, the player's view will zoom in slightly. The MAAWS can kill any juggernaut, even at full health, but it has to be a direct hit, or it won't do much damage.
The MAAWS returns in Call of Duty: Advanced Warfare. Once again it is laser-guided, but now it holds only one rocket before reloading, and it can be aimed by using the reflex sight present on the launcher's left side.

Trivia
Call of Duty: Ghosts
The number "64" is inscribed in various spots.
A multiplayer patch, requiring 25 aircraft shot down with the weapon, has a picture of a shark, referencing the movie Jaws. The terms "Maws" and "Jaws" have a similar contextual meaning.
The MAAWS used to require a 10 pointstreak instead of 9.
