"Detects lingering heat signatures from stationary enemies through materials at up to 25 meters."
Create-A-Class description.

The Millimeter Scanner (MMS) is an attachment featured in Call of Duty: Black Ops II. When a player aims down the MMS, it pulsates every two-three seconds, revealing enemies behind cover or concealed by smoke within 25 meters. However, recoil is increased but given that the player can combine the MMS with a Fore Grip to compensate for the recoil, it's not a major disadvantage. Aiming with the MMS zooms in even less than plain Iron Sights, allowing for better awareness of the players surroundings. As such, the MMS is recommended for CQB-type weapons. The MMS does not have a customizable reticle. In the mode Gun Game, the MMS is attached to the M27 at gun level 9. The MMS is available for Zombies, and is identical to the multiplayer counterpart, except that it scans moving targets.

Players cannot equip both the Millimeter Scanner and FMJ simultaneously, most likely for balancing purposes; as the MMS allows the player to see enemies through objects such as walls and with FMJ, the player could shoot through it with ease. Even without aiming, the MMS will continue to scan the area, but only within a small area, inside the scope.

Enemy players with Cold-Blooded as one of their perks will not have their character outlined through the pulse, canceling the effects of the MMS.

This attachment is rarely seen in multiplayer, most likely because it is the last weapon attachment to be unlocked at which point many players prestige their weapon, or move on to leveling up another.
