FHJ-18 AA

"Guided shoulder-mounted rocket launcher that can lock-on to enemy vehicles and turrets."

- Description.

The FHJ-18 AA is a portable anti-aircraft launcher in Call of Duty: Black Ops II, very similar to the Stinger and Strela-3. Its sole purpose is to destroy enemy scorestreaks, and it is done by aiming at them for a few seconds to lock on (The short beeps indicate it is locking, the long continuous beep means it has locked on), after which the weapon can be fired. The missile will automatically seek its target. Some scorestreaks have flares which would require more than one missile to take it down. Enemy scorestreaks are highlighted with blue circles when aiming. When the circle turns red, the FHJ-18 has locked on and can be fired.

It may be used in a class dedicated to shooting down enemy air support, such as in conjunction with Blind Eye and Cold-Blooded. While Black Hat shares a very similar role, it can be used in case the player's missiles are not enough to bring every scorestreaks down in one life.

Trivia

 * Before the 1.03 patch, the camouflage challenges required kills to obtain. As it is in practice nearly impossible to achieve kills with the FHJ-18 AA, it was later changed to aircraft destroyed.
 * The sight of the FHJ-18 AA will highlight the target it is locking on to. This is useful to spot enemy aircraft by scanning the air.
 * Although the sight will be blank, the FHJ-18 AA can work when the player is affected by an EMP.
