Vehicle mounted weapons are weapons that are mounted onto, or attached to, vehicles. The article summarizes the subject from the whole Just Cause game series.


There are multiple different types of weapons mounted onto vehicles in the Just Cause games. In Just Cause 2, some of those weapons are confusingly named the same as similarly functioning hand held weapons, hence the need for this article.

All vehicle mounted weapons had unlimited ammunition, until this was changed in Just Cause 4, tho the numbers are still high enough that a vehicle is unlikely to last long enough in combat to send it all.

Just Cause

Most vehicle mounted weapons in Just Cause do not have their own names, so they don't cause confusion with their JC2 counterparts.

In the PS2 version of the game, all vehicle mounted weapons can be switched between manual aim and auto-aim, but strangely the PC version of the game only has auto-aim. The only way to fire manually in the PC version, is when the player doesn't have Heat and is about to fire the first shot at an enemy, or when aiming somewhere, where the game doesn't detect enemies.

Harland series armoured vehicles

These armored vehicles are armed with a hull-mounted machine gun and a tank gun, multiple rocket launcher or multi-barreled heavy anti-aircraft machinegun in the turret. For more info, see the main article: Harland series armoured vehicles.

Ballard series armoured vehicles

These armored vehicles are armed with a hull-mounted machine gun and a tank gun, multiple rocket launcher or multi-barreled heavy anti-aircraft machinegun in the turret. For more info, see the main article: Ballard series armoured vehicles.

Heavy machine gun on cars and boats

Main article: Mounted Gun.

Many faction vehicles and military vehicles have heavy machine guns mounted onto them. This weapon resembles the M2 Browning. This weapon can not be fired by the vehicle's driver and require an additional crewman. They can be made useful during a Liberation, when faction members use them.

Aircraft machine guns

Nearly all helicopters have some type of machine guns. Strangely, they look like miniguns, but fire slowly like usual machine guns. What's even stranger is that they drop what should be empty cartridges, but looking closely, they're actually complete ammunition with bullets.

Aircraft rocket launchers

Helicopters and planes that have these both have identical rocket pods. Some aircraft fire only one missile at a time, some fire two, and some fire four at a time, which allows them to destroy anything in a single hit (assuming all missiles hit). Two types of heavy attack helicopter even have 8 rocket pods, but they can only fire a total of 4 missiles at a time.

Hidden weapons on cars

  • GP Thunder Extreme Prototype has 2 hidden machine guns and a hidden rocket launcher built into its front end. These weapons can be switched between and it's also possible to switch to no weapon, which is the default setting.
  • Garret Paladin has hidden machine guns in its front end. By default, they're turned off.

Triton Broadsider

The ship Triton Broadsider is equipped with a gun turret that fires similarly to the tank guns on the armored vehicles.

Just Cause 2

The vehicle mounted weapons in Just Cause 2 have their own weapon icons and names. This often causes confusion because the identically named hand held weapons have very different characteristics.

Rocket/missile launchers and rocket pods

In reality these shoot much bigger and more powerful missiles, but in the game they seem to be the same as Rocket Launchers except they fire faster, have unlimited ammunition, and don't need any form of reloading. Also, in reality, the kind of pods that can be seen on the in-game aircraft can only shoot unguided missiles that are used for ground attack missions.

Rocket pods are carried by multiple aircraft:

Rocket launchers: Other rocket launchers in vehicles can strangely fire as fast as the rocket pods, even though they only have one barrel whereas the pods have multiple. Vehicles with this weapon are MTA Powerrun 77, Poloma Renegade and Hedge Wildchild. These vehicles are only available from the Black Market and must be fully upgraded to obtain the rocket launcher. The only exceptions are the two MTA Powerrun 77s which are parked at the dock at Unnamed island at X:20400; Y:31100 and one in the mission Smugglers do Run.

Machine guns

There are several types of vehicle mounted machine guns in JC2.

  • Rowlinson K22 has dual machine guns when fully upgraded at the Black Market. Upgrading the BM version will also cause the civilian versions to start spawning with machine guns. Unfortunately, there are only 4 places where the helicopter spawns other than the BM, one of which doesn't have machine guns at level 6, and another is in a very-hard-to-find place.
  • MTA Powerrun 77 has dual machine guns in a small turret.
  • Garret Traver-Z has dual machine guns in a small turret once upgraded to BM level 6.
  • Poloma Renegade has dual machine guns in a small turret.
  • Hedge Wildchild has dual machine guns in a small turret.
  • GV-104 Razorback can be upgraded to have dual machine guns in its turret. Two already spawn with them.
  • Monster Truck has a small turret with a machine gun.

Several vehicles are armed with a "Mounted Gun", which is the same as a usual Machine Gun, but located in a shielded turret on vehicles. These mounted machine guns can not be fired by the driver and require an additional crewman. These guns are powerful enough to destroy otherwise bulletproof Sabotage Destructable Objects, but are the least threatening vehicle mounted weapons, because of how difficult it is to aim them.

Examples of vehicles with Mounted Guns: Chepachet PVD, Maddox FVA 45, Marten Storm III, MV Quartermaster, URGA-9380 (special version), and YP-107 Phoenix.

For some reason, the GV-104 Razorback and SV-1003 Raider have Miniguns, but they are referred to as a "Mounted Gun".


They fire much faster than normal machine guns and do more damage.

Grenade launchers

The Monster Truck has a small turret that fires two grenades that explode as soon as they hit. These don't fly far, so it's not advised to fire forward while moving. They're most useful for blowing up pursuing vehicles and trees while off-roading.

Auto cannon

Main article: Auto cannon.

In reality, any gun with at least 20mm projectiles that has an auto-loading mechanism is an "auto-cannon". This means that even the 4-barrel version of the Flak Cannon is by a modern definition a type of auto cannon.

Confusingly in JC2 there are two completely different weapons with this name. One type is a weapon that fires slowly one shot at a time and the other is basically a heavy, super-slow firing minigun.

Unusable weapons

The Winstons Amen 69 has unusable torpedoes and depth charges.

Just Cause 3

Some of these weapons have two sets of names. There's the HUD name and sometimes a more detailed name in the Rebel drop description.

Weapon HUD name Vehicles that have them Additional info, if needed
Light Cannon Urga Bkolos 2100.
Heavy Cannon CS Odjur.
Cannon CS7 Thunderhawk. Its actually a rotary autocannon of sorts, not a full-sized artillery mount. It appears to be identical to the "Minigun" (Urga Vulkan), in all ways except the name.
Homing Missiles CS7 Thunderhawk.
Heavy Missiles CS Navajo. These are unguided.
Missiles CS Navajo, Loochador, Weaponized Serpente. These are unguided.
Bombs U-7 Dravec.
Rockets U-7 Dravec, Urga Mstitel.
Cannon Corvette.
Machine Guns Carmen Albatross. Notice that the name is plural, unlike the ones below. That's because the vehicle has 6 of them.
Machine Gun CS Baltdjur, CS Powerrun 77, Custode 29, one version of the rebel Stria Facocero and Urga Szturm 63A. Not the same as the below version. This is the new Mounted Gun that requires you to actually man the MG in order to operate it. The weapon is in a small turret on top of the vehicle. According to writing on the magazine, it's a "W206 Mounted Capstone M2HM". Made by Capstone, it has a resemblance to the Browning M2HB. It also borrows some design cues from the 205th Armory Type 90 MG and Mauser Werke MG 42. Judging by the fact that this weapon is named so similarly to the M2HB, it is reasonable to speculate that in-univerese, it might have been a license-built M2HB, named M2HM by Capstone.
Machine Gun CS Odjur, Imperator Bavarium Tank, Weaponized Urga Ogar and possibly a few more. Not the same as the above version. This can be operated by the driver whilst driving the vehicle. It's also not entirely identical to the one above, as it has a somewhat higher rate of fire.
Autocannon Mech.
Fire Leech Mech. Not the same as the hand held Fire Leech rocket launcher.
Bavarium Splitter Mech. This is much bigger and more powerful than the hand held Bavarium Splitter.
Minigun(s) Urga Postolka, Urga Hrom D, Urga Mstitel, Weaponized Pescespada SS, Loochador, and possibly a few more. These are Urga Vulkans. They are controlled from the driver seat.
Tank cannon small (never found in game) Urga Bkolos 2100. This weapon name is Cut game content from Just Cause 3. It was renamed before the game launch.
Anti-surface missiles (never found in game) U-7 Dravec. This weapon name is Cut game content from Just Cause 3. It was renamed before the game launch.

The Rebel drop descriptions reveals longer realistic weapon names for some vehicles:

  • Urga Hrom D description: "The Urga Hrom D is pure mayhem with a rotor on top. With the Janus-88M-Minigun and 95 Volcanus missile pre-loaded, it can make whole bases disappear in seconds."
  • CS7 Thunderhawk description: "When it comes to aerial firefights, few top the CS7 Thunderhawk, featuring the M98 machine gun, M62 Mako repeating missiles and M-78 Kauga heat-seekers."
  • Urga Postolka description: "This light assault helicopter is equally equipped to handle patrol detail, base sieges, or air-to-air firefights. It comes equipped with the Janus-45S minigun."

There is a EDEN Corporation Urga Szturm 63A in the game files that was meant to spawn as a wreck at the bottom of Stingray and at an eDEN science station somewhere on Insula Lacrima. It was meant to have a different design and functionality, among these differences is an AA emplacement on it instead of the standard turret. Its unknown what the AA would have looked like. See also: Cut game content from Just Cause 3.

Just Cause 4

Several Vehicles in Just Cause 4 have mounted weapons. Most are military vehicles, but some are modified civilian vehicles.

A significant difference from the previous games is the fact that all vehicle mounted weapons now have limited ammunition.

Many items are given the same name, but are different.

Weapon HUD name Vehicles that have them Ammo capacity Additional info, if needed
Machine Gun Reptile AAV. 1600 Slow-firing, high damage machine gun. Controlled from inside.
Machine Gun Cavalry Armored Truck. 1600 Slow-firing, high damage machine gun. Externally mounted.
Cannon Falconer AA Tank. 300 Technically 75 shells per cannon. Surprisingly powerful, despite being small-caliber, scaled down autocannons.
Cannon Pointman Scout Tank. 300
Cannon Prizefighter Tank. 300
Machine Gun Prizefighter Tank. 1600 Slow-firing, high damage machine gun. Controlled from inside.
Cannon Warchief Assault Tank. 300
Machine Gun Warchief Assault Tank. 1600 Slow-firing, high damage machine gun. Controlled from inside.
Machine Gun PA Microfighter. 1600 Faster-firing machine gun with tracer rounds and a different sound effect.
Machine Gun Fellhawk Jet Fighter. 1600 Faster-firing machine gun with tracer rounds and a different sound effect.
Missiles Fellhawk Jet Fighter. 30 These are guided fire-and-forget missiles, but require an initial lock-on from the pilot operating it for it to chase the target. Fires four missiles at once, but this only reduces ammunition count by two. This means 15 salvos total.
Machine Gun Thunderhead Bomber Jet. 1600 Faster-firing machine gun with tracer rounds and a different sound effect.
Carpet Bomb Thunderhead Bomber Jet. 60 Drops several bombs per bombing run. It is unknown how many ammunition units a single bombing run reduces.
Cannon Longbow Cannon Truck. 300 Very large and powerful artillery gun. Strangely it deals much less damage and has a much smaller blast radius than one would expect from the massive shell it fires.
Cannon Trains and railroads in Solís. 300 Massive artillery gun mounted on trains that is very powerful. Both basic Black Hand and Sandstinger versions have 300 rounds, meaning 150 each for the Black Hand version.
Machine Gun Firebrand Scout Chopper. 1000 A third type of machine gun. Appears to be a minigun. Pre-release screenshots showed a third nose-mounted minigun, so it's unknown if there was going to be 1500 rounds.
Missile Spectre Attack Helicopter. 100 These are unguided.
Missile Bloodhound Siege Heli. 100 These are unguided.
Machine Gun Bloodhound Siege Heli. 1600 A third type of machine gun. Appears to be a minigun
Machine Gun Daggershark Jetboat 1600 Slow-firing, high damage machine gun.
Machine Gun Stormwater Patrol Boat 1600 Slow-firing, high damage machine gun. Externally mounted.
Mortar Stormwater Patrol Boat 50 Not a mortar at all. It is actually a missile launcher. When used against surface targets it fires missiles in an artillery-like trajectory.
Machine Gun Thunderbarge 1600 Slow-firing, high damage machine gun. Externally mounted.
Mortar Thunderbarge 50 (infinite in the mission) Same mortar as the Stormwater Patrol Boat: not a mortar, but a missile launcher.
Ion Coil Thunderbarge N/A Technically not a weapon, but it absorbs lightning, making this vehicle the only one that is immune to lightning.

Dare Devils of Destruction DLC

The DLC includes a number of weaponized sports cars. The letter at the end of the name indicates the upgrade level. B is the entry-level, A improves the vehicles statistics and S adds wheels spikes (spear tips in the wheels, like on Roman chariots). Some vehicles get dual miniguns at S level.

  • "Azor Stylex B" hatchback racecar with dual SMGs on the hood and small rocket engines to help with drifting.
  • "Sol Velocista-B" with dual SMGs on the hood and grenade launchers to eliminate vehicles from behind you.
  • "Excorpión Scatterbane B" - Muscle car with dual shotguns on the hood.
