FHJ-18 AA

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

- Description.

The FHJ-18 AA is an anti-aircraft launcher in Call of Duty: Black Ops II, very similar to the Stinger and Strela-3.

Campaign
DeFalco or a militiaman will use the FHJ-18 AA to shoot down an American/Yemeni VTOL in the beginning of Achilles' Veil. Raul Menendez later uses the FHJ-18 AA to shoot down Harper's VTOL later in the level.

Multiplayer
The FHJ-18 AA is available to unlock for an unlock token at level 4, it is also part of one of the preset classes. The FHJ-18 AA's 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 AA has locked on and can be fired.

It is better used in a class dedicated to shooting down enemy air support, such as in conjunction with the Blind Eye and Cold-Blooded perks. While Black Hat shares a very similar role, it can be used in case the player's missiles are not enough to bring every Scorestreak 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 will work when the player is affected by an EMP.
 * The pick-up icon for the FHJ-18 AA in the single player campaign is the Strela-3 from Call of Duty: Black Ops.
 * There is Chinese writing on the launcher's rocket tube.
