The Millimeter Scanner, or 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 provided they are stationary or are moving at speeds similar to aiming down sights with an LMG while crouched. Aiming with the MMS zooms in even less than plain Iron Sights, allowing for better peripheral vision with the cost of less long-range effectiveness. As such, the MMS is recommended for close quarters-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. This makes it incredibly useful in Green Run, where the thick fog makes it nearly impossible to see zombies any significant distance away.
Players cannot equip both the Millimeter Scanner and FMJ simultaneously, most likely for balancing purposes. Although the MMS cannot be paired with FMJ, it can be equipped on the SWAT-556 and SMR assault rifles which have the same level of penetration as Light Machine Guns. Another viable weapon for the MMS is the KSG shotgun which has very high penetration, including the ability to one shot kill through walls. Even without aiming, the MMS will continue to scan the area and spot enemies, but only within a small area, inside the scope. As the Millimeter Scanner is placed some how higher, the amount of visual muzzle flash is decreased, but not as much as EOTech sight. It is also near as clear as the reflex sight but (still) it should be used for submachine guns
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.
- If a weapon with Gold Camouflage with MMS attached, the glass will be golden instead of clear when viewed in third-person.
- Since the MMS constantly pulses, it is possible to see stationary or slow moving players through walls without even aiming down the sight, provided the player is in the field of view of the MMS.
