The gun is also fully stabilized, with a similar handling akin to that of the [[HSTV-L]]; slower than the [[M163]] and [[M247]] Sergeant York but still fast enough to react to most aerial targets at close range, particularly helicopters and slow and low flying jets. Like most other AAs, it comes with a Default, AP, and HE belt. The Default belt has a 1:1 AP to HE ratio and is the only belt the vehicle has access to. The HE belt has a 3:1 HE to AP ratio while the AP belt has a 3:1 AP to HE ratio. The former is more effective against aircraft while the latter is more effective against armored vehicles. The AP round is the same across all belts, and can penetrate 91mm of armor at point blank range. Combined with the relatively high fire rate, it can easily destroy barrels, tracks, and machine guns with ease. | |

Description
The LAV-AD is a rank VII American SPAA with a battle rating of 9.7 (AB) and 10.0 (RB/SB). It was introduced in Update "Wind of Change".
General info
Survivability and armour
Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.
Armour type:

Armaments
Main armament
The main armament of the LAV-AD is the 25mm GAU-12U rotary autocannon. It functions similarly to the 20mm M168 Vulcan found on the M163 earlier on in the tech tree, but with a reduced ammo capacity of only 1000 rounds total (500 ready, 500 reserve instead of 1,100 ready, 1,100 reserve) and fire rate (1,800 rpm instead of 3,000 rpm) due to the limited room in the vehicle and larger caliber ammunition. The gun is also fully stabilized, with a similar handling akin to that of the HSTV-L; slower than the M163 and M247 Sergeant York but still fast enough to react to most aerial targets at close range, particularly helicopters and slow and low flying jets. Like most other AAs, it comes with a Default, AP, and HE belt. The Default belt has a 1:1 AP to HE ratio and is the only belt the vehicle has access to. The HE belt has a 3:1 HE to AP ratio while the AP belt has a 3:1 AP to HE ratio. The former is more effective against aircraft while the latter is more effective against armored vehicles. The AP round is the same across all belts, and can penetrate 91mm of armor at point blank range. Combined with the relatively high fire rate, it can easily destroy barrels, tracks, and machine guns with ease.

Additional armament
The LAV-AD also comes with FIM-92 Stinger missiles. The missiles are IR guided, meaning they require a lock-on before firing. The vehicle has FIM-92Es by default and can unlock FIM-92Ks as a later modification. These are the same Stinger missiles used by the Ozelot in the German tech tree and function the same way. The missiles count as special weapons.

Usage in battles
Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).
Pros and cons
Pros:
- Has access to Hydra 70 rockets
- The 25 mm GAU-12U cannon shreds any air vehicles in its range
- Highly mobile thanks to its light weight and is also amphibious
- Can get two SAM launchers if you choose to not have Hydras on the vehicle
- Has access to 2nd generation thermal sights for the gunner
- Has optical tracking meaning air targets will not receive RWR pings when locked onto
- Comes with smoke grenades stock
- Laser rangefinder automatically adjusts the sights, unlike on the M247 and ADATS
Cons:
- The SAM has only a maximum overload of 10G which may prove difficult against planes with high maneuverability.
- Long reload for the 25mm gun
- Cannot use two Stinger pods and Hydra rockets at the same time; one of the two setups must be chosen
- Turret crew easily die to heavy machine gun fire and is prone to overpressure
- Shorter range when compared to its contemporaries like the Roland 1, FlaRakPz 1, and XM975 at the same BR
- MAW detects missile launches and Stingers are prone to being diverted by flares
- No search radar
- No proximity ammunition unlike the preceding M247
- Hydra rockets are hard to aim due to their low velocity and do not work properly with the laser rangefinder
History
Devblog
Development of the LAV-AD began in 1987 after a contract was signed with both the FMC Corporation and General Electric to design a SPAA variant for the LAV-25 for the USMC. Both companies began developing a system based on the USMC requirements that it had to be armed with a 25 mm cannon and possess provisions for mounting Stinger missiles and Hydra-70 rockets. While the FMC company opted to outfit their design with the same M242 cannon used on the base model of the LAV-25, General Electric decided to go for the GAU-12 ‘Equalizer’ Gatling style rotary cannon.
Having reviewed both prototypes, the USMC decided to procure General Electric’s design, placing an initial order for 125 vehicles to be produced. By 1996, the LAV-AD had formally been adopted into service. Despite the initial plans to produce over 100 vehicles, only 17 were actually manufactured due to funding issues. In 1998, the final unit was delivered to the USMC and further development of the vehicle was discontinued due to high maintenance costs. Among other operations, the LAV-AD was used in combat action in Iraq.
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
