Soldiers operating a 40mm Bofors.

The 40mm Bofors Anti-Aircraft Gun is a flak cannon used for anti-aircraft purposes. It is featured in the Battlefield Series as stationary or unusable emplacements.

Battlefield 1942[]

"The AA gun is one of the best defenses against enemy airplanes. But be careful, the flak does not discriminate between friendly and enemy airplanes. It can also be used against ground forces when employed correctly."

— Tooltip, AA GUN

The AA_Allies[sic] is the Allied anti-aircraft emplacement, the equivalent of the Axis Flak 38. The emplacement appears on every map where aircraft is available to players. It spawns near most flags, main bases, and on the Enterprise- and Shōkaku-class carriers.

The gun itself fires powerful anti-aircraft rounds at a slow rate. It has an unlimited ammunition supply, does not need to reload and does not overheat, meaning the gunner can fire for as long as he wishes (or as long as he remains alive).

Its rounds are capable of disposing quickly of low-flying aircraft, destroying fighters in about 4 direct hits, dive bombers in around 5 and a lot more than that for heavy bombers. They also cause some splash damage, so one might not rely on direct hits to down a plane. Aircraft at higher altitude can be more difficult to engage, since one has to take the round's velocity into account and predict the aircraft's flight path.

The gun is also fatal against infantry it can hit with one direct hit killing any player. It also takes care of light vehicles like jeeps and APCs quickly. Tanks need quite some fire to be taken down, and by that time, the gunner will most likely be killed. It should be noted however, that the emplacement is commonly surrounded by objects such as sandbags preventing bullets to be fired parallel to the ground.

The only differences from the Flak 38 are in aesthetics and optical sights.


Battlefield Vietnam[]

The AA_Allies returns in the Battlefield Vietnam World War II Mod as the anti-air emplacement of the U.S. Marines. It performs identically to, and is found in the same locations as, the counterpart in Battlefield 1942.

Battlefield 1943[]

The 40mm Bofors is an anti-aircraft gun featured in Battlefield 1943 It can be found on bunker roofs and aircraft carriers.

Its slow bullets deal high damage to aircraft and light vehicles such as jeeps, whereas a tank can come out of a barrage unscathed. It can combat infantry though it is difficult with infantry being a small target. Users are very vulnerable as well, as there is little protection from all sources of damage.

Battlefield: Bad Company 2[]

The 40mm Bofors makes an appearance in Battlefield: Bad Company 2 during Operation Aurora. It is operated by the Imperial Japanese Navy to fire on the incoming American aircraft. It is never available to the player.

Battlefield 4[]

Main article: AC-130 Gunship

The 40mm Bofors is one of three ground-attack weapons carried aboard the AC-130 Gunship featured in Battlefield 4. (It does not appear in the Battlefield 3 version.)

Battlefield V[]

In Battlefield V, the Bofors can be found as both a standalone anti-aircraft emplacement, as well as a vehicle armament.

40mm AA[]

"One of the most well known and widely used anti-aircraft guns during the war. Despite being primarily employed by the British several of these autocannons were captured by Axis forces some of which began manufacturing their own version."

— In-game description

The 40mm AA is a stationary weapon featured in Battlefield V, added with the War in the Pacific Tides of War chapter. It is the factional anti-aircraft emplacement of the United Kingdom, USA and Japan, and the equivalent to the German Flak 38.

Compared to the Flak 38, the 40mm has about half the rate of fire at 120 RPM and can only fire around 15 shots continuously before overheating, but has much greater impact and airburst blast damage, and is more than capable of destroying a full health aircraft without overheating. It can also kill an infantryman in two shots or a single headshot. Projectile velocity and blast radius are otherwise identical to the Flak 38.

Vehicle Mounted 40mm AA[]

The weapon is also the default main gun on the British anti-aircraft tank, the Valentine AA Mk I, known also as the 40mm AA. Through specializations, it can be replaced with 3x Oerlikon 20mm guns.


  • In Battlefield V, the 40mm AA gun lacks a gunshield, but its wreck has one when destroyed as does its ghost when building one using Fortifications.
  • in Battlefield V, the spent shells come out a chute in the bottom.
