Multi-turreted/cannons tanks

In this guide I will list all tanks with several cannons OR similar armaments. Therefor you will not find tanks on this list with several turrets, where their armaments are machineguns or of a lesser caliber. I am strictly listing tanks where their secondary armament can reliably be used in tank to tank warfare.

Tanks with rockets (as a secondary armament) or very high caliber machineguns (as a secondary armament) will also be on the list, as they can be used to fight other tanks.

Enjoy

USA

M3 LEE
The Medium Tank M3 Lee is a rank II American medium tank with a battle rating of 2.7 (AB/RB/SB). This tank was one of the first American tanks to be released with the American ground tree in Update 1.45 "Steel Generals". The M3 Lee gives the player a substantial upgrade in firepower and armour compared to the M2 Medium and M2 Lights with a combination of 37 mm and 75 mm cannon on the tank. The two guns make this tank awkward and hard to control for a new player but will give an edge when its handling and operation are mastered properly.
The M3 Lee is most well recognized for its tall profile and two cannons. The suspension resembles that of the M4 Sherman, the only notable difference being the return rollers' positions. The hull front is also stepped into two plates, where the upper is closer to vertical. The large sponson on the right side of the tank carries the main 75 mm gun; note that with 2 crew, it is the operational gun. The 37 mm gun is in a turret, mounted with a leftward offset, and has a small MG cupola on top.

GRANT 1
The Grant I is a premium rank II American medium tank with a battle rating of 2.7 (AB/RB/SB). It was introduced along with the initial American ground tree in Update 1.45 "Steel Generals" as a bundle vehicle, but was later removed from the store. It was reintroduced for War Thunder's 6th Anniversary as a premium purchasable for 1,000 Golden Eagles . It is a modified version of the M3 Lee in the American medium tree line with a redesigned turret made for the British Army.
The Grant is most well recognized for its tall profile and two cannons. The suspension resembles that of the M4 Sherman, the only notable difference being the return rollers' positions. The hull front is also stepped into two plates, where the upper is closer to vertical. The large sponson on the right side carries the main 75 mm gun; note that with 2 crew, it is the operational gun. The 37 mm gun is in a turret, mounted with a leftward offset. Its main notable difference from the M3 Lee is a redesigned turret.
Due to the presence of two cannons, this tank is an excellent multi-role vehicle. The Grant can be played it as a brawler combining the agile 37 mm gun with the high damage of the 75 mm gun, but don't get too close, in fact, the turreted gun has a bad depression and, combined with the high profile, tends to make close tanks difficult to hit. Note that the different guns can be assigned different keys to be separately used, so it is possible to select the 75 mm as a primary weapon, allowing the optics to accommodate the 75 mm shells (and not from the point of view of the 37mm gun) and use the bullet drop indicator in arcade battles.

M6A1
The Heavy Tank M6A1 is a rank III American heavy tank with a battle rating of 4.7 (AB/RB/SB). It was one of the first American tanks to be released with the American ground tree in Update 1.45 "Steel Generals". A rather unusual tank design mounting two cannons in the turret, however, it has a durable frontal armour for the battle rating it occupies.
The M6A1 is one of the most unique tanks in the game, with its large hull and being as tall as a Tiger I. Another interesting feature is that it is one of the most manoeuvrable heavy tanks in the game with a powerful Wright G-200 engine (the same engine powering the B-17 Flying Fortress bomber) with a max speed of 35 km/h, making it very mobile in a battle situation. The tank has two 12.7 mm's in the hull which are effective for taking out lightly armored vehicles such SPAAs. The M6A1 is one of the first American tanks as well in the game to have the transmission at the rear of the tank.
Something to keep in mind is the shell arc of the secondary 37 mm cannon. Its shell will usually hit the same spot on distances up to 1400 m (~1 mile). But do not forget that the gun is offset to the left in close combat, or it will not hit the target.

Calliope
The Rocket Launcher T34 Calliope is a premium rank III American medium tank with a battle rating of 4.3 (AB) and 4.0 (RB/SB). It was introduced in Update 1.49 "Weapons of Victory". Though using the base model of a M4 Sherman, it has a 60 round rocket rack sitting above the turret that fires 114 mm rockets at a general location. While giving the team a good edge in firepower, the rocket rack also presents a large weak point that can be targeted with a high-explosive round for an ammo-rack detonation.

M26 T99
The Medium Tank M26 T99 is a premium rank IV American medium tank with a battle rating of 6.3 (AB/RB/SB). It was introduced in Update 1.53 "Firestorm". This is a M26 Pershing tank equipped with four rocket pods holding a total of 44 rockets which can be launched against the enemy.

MBT-70
The 152-mm Gun-Launcher Main Battle Tank 70 (shortened as MBT-70) is a rank VI American medium tank with a battle rating of 9.3 (AB/RB/SB). It was introduced in Update 1.71 "New E.R.A.". Comes equipped with a 20 mm Rh202 cannon as its secondary armament


M3 Bradley
The Fighting Vehicle, Cavalry, M3, or M3 Bradley, is a rank VI American light tank with a battle rating of 8.0 (AB/RB/SB). It was introduced in Update 1.85 "Supersonic". Has a light auto cannon and anti tank guided rockets.

M60 AMBT
The M60 AMBT is a gift rank VII American medium tank with a battle rating of 10.0 (AB) and 9.7 (RB/SB). It was introduced during Update "Starfighters" as a reward for World War Mode Season 3: Road to the West.

The M256 is the same cannon that is used on the M1A1 and M1A2 Abrams. The main item that differentiates this cannon from the M1A2's is the round. The M60 AMBT has the "KE-W" APFSDS round which has very high penetration for its BR. The round can be reliably shot centre mass and penetrate most opponents it faces, excluding the top BR tanks in a full uptier. 583 mm at 0° point-blank is an extremely potent round for most engagement ranges you will experience. The AMBT Also has access to the M830 HEAT-FS round which can be useful for killing lightly armoured vehicles and destroying some map obstacles such as buildings or trees. The M60 AMBT also has decent gun handling up its sleeve, it is not the fastest at the B

GERMANY

E-100
The Pz.Kpfw. E-100 is a gift rank V German heavy tank with a battle rating of 8.0 (AB) and 7.7 (RB/SB). It was introduced in Update 1.53 "Firestorm". Like the Maus, the E-100 carries the 128 mm KwK 44 gun that can annihilate anything it penetrates. The E-100, like the Maus, also has a coaxial 75 mm with HEAT ammunition for lesser targets so the limited 128 mm shells (42 of them) are not wasted. The 75 mm also can fire smoke round so it is possible to keep a secondary ready with smoke while moving around with an AP round in the main gun.

SPz BMP-1
The SPz BMP-1 is a rank V German light tank with a battle rating of 7.3 (AB/RB/SB). It was introduced in Update 1.93 "Shark Attack". The 2A28 main cannon, despite being the 'main' armament will more often than not act more as secondary armament, at least once the BMP-1P upgrade is researched, due to the 9M113 ATGM proving significantly more controllable and effective at all engagement ranges. Despite this, the PG-9 HEAT round proves valuable in a pinch, with well-placed shots able to disable critical components on most vehicles the SPz BMP-1 will face. The SPz BMP-1 comes with a rail-mounted manually-guided ATGM as stock, initially aimed manually and with somewhat mediocre penetration and explosive mass values. While occasionally useful, generally the main gun is easier and more reliable to use.

Begleitpanzer 57
The Begleitpanzer 57 is a rank VI German light tank with a battle rating of 8.3 (AB/RB/SB). It was introduced in Update 1.73 "Vive la France". As a light tank, the Begleitpanzer 57 carries a great firepower punch for its mobility despite its lack of armour. A rapid firing 57 mm cannon carries enough penetration rivaling that of the ZSU-57-2, but the addition of a TOW launcher system makes this vehicle a dangerous opponent by being able to engage a variety of target at its leisure.
While the cannon shares the calibre with the Russian 57 mm gun, it is quite different in performance. The Russian SPAA has a slightly better combined fire rate and significantly more accuracy at range. You also start to lose the penetration advantage at 1 km compared to the APHE belt of the ZSU-57-2. All of this combined makes you very reliant on your ATGM, of which you only have 6. Upgrading to the better ATGM is highly encouraged, the APHE belt can be completely ignored as it can not reliably perforate Russian side armour.


KPz-70
The KPz-70 is a rank VI German medium tank with a battle rating of 9.3 (AB/RB/SB). It was introduced in Update 1.71 "New E.R.A.". KPz-70 is one of the few medium tanks (aside from French and MBT-70) to carry 20 mm coaxial autocannon. This weapon should not be treated lightly or dismissed as "just an anti-aircraft" gun, as it has 57 mm penetration at flat angle, and it will shred anything from light tanks and SPAA, to lightly armoured medium tanks' sides and SPG, if they are not angled. In case that their armour cannot be penetrated, use the autocannon to destroy a hostile tank's gun barrel and make them helpless, then return fire. This is even more effective, considering the main cannon can fire ATGM directly at enemy tank without losing the penetration or accuracy even when its barrel is broken, allowing you to punish people fishing for easy cannon barrel takedowns.

Maus
The Pz.Kpfw. VIII Maus is a rank V German heavy tank with a battle rating of 8.0 (AB) and 7.7 (RB/SB). It was introduced in Update 1.47 "Big Guns" as a main tree vehicle, however as of Update 1.91 "Night Vision" it was shifted to become a gift vehicle for players who previously owned it. It was later reopened to research for a limited time during War Thunder's 8th anniversary. The Maus is the definitive tank of heavy armour in Rank V and is the largest ground vehicle in game. Coaxial LMG? Pff, that's for normal tanks (But it is there anyway). On the Maus, everything is bigger. The short 75 mounted alongside the main 128 originally served as anti-infantry and soft target weapon of choice. In War Thunder, these vehicle types are either not found on the battlefield or as latter only on certain maps. It comes without question that the 75 mm should be used against AAA, trucks and SPAA. However, the HEAT shell can be used to harass the enemy, lure them out/in of cover, or just damage medium tank's sides (T-54 and M46 do not exceed 80 mm of armour) tracks and even hull break some lightly armoured vehicles such as the BMP 1. In addition, the secondary cannon has a good reload rate of around 5 sec, thus it can be used to defeat light tanks and SPAA without wasting the precious 128 mm ammo for more heavily armoured targets.

USSR

RBT-5
The RBT-5 is a premium gift rank I Soviet light tank with a battle rating of 1.3 (AB/RB/SB). It was available as a prize during the 2016 "Thunder League" eSports tournament as a giveaway prize for watching the Twitch stream, later every Dog-Tag owner who voted for Team Dislike earned one due to the "Champion" prize. It is currently available through the Gaijin store for individual sale or through the 'Project-X' trophy.
The RBT-5 is a regular BT-5 with the mounts to hold two 250 kg TT-250 torpedoes modified as rockets. The large calibre rockets prove hard to aim, but a real dealer to anything it hits.


T-35
The T-35 is a premium rank I Soviet heavy tank with a battle rating of 1.3 (AB/RB/SB). It was introduced in Update 1.43. The T-35 has the distinction in-game as the vehicle with the most crew members (10 total). While the armour may not provide great protection against enemies even at Rank I, the large crew count makes up in part for the tank's survivability in combat.
The T-35 is large. It has five turrets on top, but only three should be taken into consideration: the one in the middle, the one front right from the middle, and the one bottom left from middle, all due to their armaments being able to destroy tanks. However, don't be deceived by its size - the T-35's armour is barely more than 30 mm thick. Even with a standard Rank I gun, you may be able to penetrate its armour.
Despite the huge ammo reserve for the secondary turrets, the total ammo is split between the two turrets. This means that if one 45 mm cannon fires more than the other, it will run out and be unable to fire until resupplied.
The T-35 is the largest tank among the Rank I vehicles. With a multi-turreted platform of two 45 mm cannons and one 76.2 mm cannon, the tank can combat enemies at an almost 360° angle. However, the armour is quite thin for a vehicle of its size so one should not play this vehicle like a typical heavy tank later down the rank. The speed is decent for a vehicle of its size, however, so it is possible to catch the enemies off guard by attacking from an area they least expect.

M3 Medium (USSR)
The ▂M3 Medium is a premium gift rank I Soviet medium tank with a battle rating of 2.7 (AB/RB/SB). It was introduced during Update 1.55 "Royal Armour". It was first obtained via the special event "Defender combined battles" in 20 February 2016 and has been occasionally available to be obtained since, primarily in the September "Tanker's Day" events in 2016 and 2017.
Aside from the paint job, the M3 Medium is virtually identical to the American M3 Lee; the different name comes from the Russian designation of just "M3 Medium". The M3 is most well recognized for its tall profile and two cannons. The suspension resembles that of the M4 Sherman, the only notable difference being the return rollers' positions. The hull front is also stepped into two plates, where the upper is closer to vertical. The large sponson on the right side of the tank carries the main 75 mm gun; note that with 2 crew, it is the operational gun. The 37 mm gun is in a turret, mounted with a leftward offset, and has a small MG cupola on top.

SMK
The SMK is a premium rank II Soviet heavy tank with a battle rating of 3.7 (AB/RB/SB). It was introduced in Update 1.45 "Steel Generals". The SMK was named after Sergei Mironovich Kirov, an early Communist Party official who was assassinated in 1934. A twin-turret heavy tank, the SMK provides an interesting play style to its users. Only one prototype was built before the project was dropped.

BMP-1
The BMP-1 is a Rank V Russian light tank with a battle rating of 7.3 (AB/RB/SB). It was introduced in Update 1.71 "New E.R.A.".
The BMP-1 is a shoot-and-scoot type of vehicle as an exposed BMP-1 is a dead BMP-1 - avoid being a target at all costs. Use your mobility to find reasonable sniping spots (for your ATGM) and only use your cannon if an enemy is close and unaware of your presence. Remember that if anything sees you, it can destroy you - even a .50 cal will make quick work of the BMP-1 from the sides or back.

BMP-2
The BMP-2 is a rank VI Soviet light tank with a battle rating of 8.3 (AB/RB/SB). It was introduced in Update 1.81 "The Valkyries". The Shipunov 2A42 30 mm Autocannon is a very versatile weapon - it is possible to change its fire rate based on the situation and it has vertical guidance of +74 degrees, which makes it effective not only against tanks but for planes and helicopters as well. BMP-2 also has an ATGM launcher. Its guidance system is semi-automatic, so it's easier to use in RB. It is a default modification on the vehicle, unlike the BMP-1, so doesn't need to be researched.

BMP-2M
The BMP-2M is a squadron rank VII Soviet infantry fighting vehicle (light tank) with a battle rating of 8.7 (AB/RB/SB). It was introduced during Update "Starfighters". The vehicle's playstyle is relatively similar to the BMP-2's. The fast turret traverse speed, wide field of view, and thermals for the optics combined with a fast-firing 2A42 autocannon and four 9M133 ATGMs makes it an excellent close range combat IFV and good front line scout at open fields.

BMP-3
The BMP-3 is a rank VI Soviet light tank with a battle rating of 8.3 (AB) and 8.7 (RB/SB). It was introduced in Update 1.93 "Shark Attack". Main armament consists of a 2A70 100 mm gun - which can fire ATGM's - and a co-axial 2A72 30 mm autocannon. Secondary armament consists of a co-axial 7.62 mm machine gun. The armament is housed in a round, centrally mounted, turret. Power is provided by a UTD-29 450 hp engine, while later in production it received a UTD-29M 500 hp engine. The BMP-3 is also amphibious, propelled by its spinning tracks.

GREAT BRITAIN

Grant I (Great Britain)
The Grant I is a premium gift rank II British medium tank with a battle rating of 2.7 (AB/RB/SB). It was introduced during Update 1.61 "Road to Glory" in the Operation S.U.M.M.E.R. event of 2016. The Grant Mk I has only been available in Operation S.U.M.M.E.R. of 2016 that lasted from 22 July to 22 August. It was unlocked after obtaining 18 tanker Marks of Distinction. It is identical to the American Grant I, which itself is nearly identical to the M3 Lee with the difference being in the different turret design.
The Grant is most well recognized for its tall profile and two cannons.

Churchill I
The Tank, Infantry, Mk IV, Churchill I (A22) (or just Churchill I) is a rank II British heavy tank with a battle rating of 3.0 (AB/RB/SB). It was introduced in Update 1.69 "Regia Aeronautica" along with the Vickers MBT and Chieftain Mk 5 as an expansion to the British tech tree. Like the original model of the Churchill infantry tank, it has the substantial frontal armour able to withstand enemy shells.
The Churchill Mk I is one of the more capable heavy tanks at rank II. The tank has excellent frontal armour that can absorb and bounce shots. Tanks such as the Panzer III, T-34, M4 Sherman, and even the dreaded Panzer IV F2 can be blocked if angled. Very few tanks can deal with the Churchill Mk I effectively from the front, such as the M10 or Achilles. Its 2-pounder gun, however, is very underpowered for its battle rating. It is of small calibre and low penetration and damage. Its secondary howitzer is also nearly useless as it only has HE shells.

Cromwell V (RP-3)
The Tank, Cruiser, Mk VIII, Cromwell V (A27M) (RP-3) (or just Cromwell V (RP-3)) is a premium rank II British medium tank with a battle rating of 3.3 (AB/RB/SB). It was introduced in Update 1.59 "Flaming Arrows". Equipped with four 152 mm RP-3 rockets with a relatively straight trajectory, the Cromwell RP-3 could be played with more precision than its other rocket-bearing contemporaries like the T34 Calliope. The 75 mm gun can help do damage to tanks of the same class like the Panzer IV, using its speed to get to an angle to hit the weaker points of the enemy tanks.

Warrior
The Combat Vehicle, Personnel, Tracked, 30mm Gun, Warrior FV510 (or just the Warrior) is a rank VI British light tank with a battle rating of 8.0 (AB/RB/SB). It was introduced in Update 1.81 "The Valkyries". Warrior is basically a big box with a round turret, which has a little gun in middle, "ears" (ATGM cameras), and the ATGM launcher itself on the right side. Front of the hull is sloped to decrease small firearms damage. IFV hull is huge compared to even medium tanks of some factions (about double the size of T-62) and looks even bigger when carrying additional armour. The Warrior is mostly played as an aggressive ATGM tank or ambush scout tank, though it can fulfil any role that doesn't involve it being constantly shot at.
It's best described as a hybrid between a slowed down SPAA and assault ATGM launcher.

JAPAN

Ro-Go
The Type 95 Ro-Go is a premium rank I Japanese heavy tank with a battle rating of 1.3 (AB/RB/SB). It was introduced in Update 1.67 "Assault". The Type 95 Ro-Go, like most landships, is the perfect vehicle to lead an assault. It can take a beating due its relatively thick armour and with the crew placement it shouldn't be an easy task to simply knock it out with a single shell. The tricky part about the Ro-Go is the difference between shell velocities of the two cannons, the 70 mm has an abysmal muzzle velocity and quick drop off rate with 300 m/s on the Type 95 APHE and a mere 200 m/s on the Type 3 HEAT while the secondary cannon, a 37 mm Type 94, found on the Type 95 Ha-Go has 575 m/s. As last armament to mention the Ro-Go has a MG turret in the back of the tank, which in-game won't really see much use and can be seen as a safe spot for the last crew member, but in-case a light armored truck tries to flank the Ro-Go and no-one is covering the back, as last resort the MG could prove handy.

Chi-Ri II
The Type 5 Chi-Ri II is a rank III Japanese medium tank with a battle rating of 5.0 (AB/RB/SB). It was introduced along with the initial Japanese Ground Forces tree in Update 1.65 "Way of the Samurai". It's armed with a Type II Model I 75 mm cannon and is the first tank in the game to feature a fully functional auto-loader for full-size tank guns, giving it a two round capacity.
The Chi-Ri II is quite a unique tank to use in the game, presenting its own set of intriguing features as well as faults. On one hand, the Chi-Ri II has an auto-loading high-penetrating 75 mm gun that allows it three shots in rapid succession. However, the tank's very large size and relatively thin, flat armour means it must be played very carefully. secondary 37 mm hull gun

Type 89
The Type 89 is a rank VI Japanese light tank with a battle rating of 8.3 (AB/RB/SB). It was introduced in Update 1.85 "Supersonic".
The full name is known as the Mitsubishi Type 89 infantry fighting vehicle (Japanese: 三菱89式装甲戦闘車 - Mitsubishi 89-shiki sōkō-sentō-sha), the Type 89 provides an autocannon weapon combined with an anti-tank guided missile for a diverse range of attack methods.

CHINA

ZBD86
The ZBD86 is a rank V Chinese light tank with a battle rating of 7.3 (AB/RB/SB). It was introduced in Update 1.91 "Night Vision".

A Chinese variant of the BMP-1, the ZBD86 is externally identical to the original Soviet version when stock. But this vehicle has a hidden secret: as of Update "Raining Fire", the ahistorical BMP-1P modification has been replaced with the "ZBD86 Late". This equips it with the HJ-73E ATGM, a very powerful derivative of the original "Malyutka" with SACLOS control and a tandem warhead. As the ZBD86 is currently the last Chinese light tank in the game, the HJ-73E allows it to remain useful even when brought to higher tiers.

ITALY

M14/41 (47/40)
The Fiat-Ansaldo M14/41 (47/40) is a premium rank II Italian medium tank with a battle rating of 2.3 (AB/RB/SB). It was introduced in Update "Regia Marina". This tank is a one-off modification of the in-tree M14/41 with the 13.2 mm hull-mounted coaxial machine-gun which can be useful, but it is purely situational, and an upgraded main gun (the same as mounted on the M15/42).

FRANCE

B1 bis
The Char de bataille B1 bis (Battle tank B1 "repeated") is a rank II French heavy tank with a battle rating of 2.3 (AB/RB/SB). It was introduced in Update 1.75 "La Résistance". With arguably the best armour at its BR, this tank is a beast in long-range engagements since it is hard to penetrate at distances. While not having the best armament, it should do the job taking care of these dangerous early SPGs and light tanks. The "bis" suffix is a French way of marking an improved version.

B1 ter
The Char de bataille B1 ter (Battle tank B1 "tertiaire") is a premium rank II French heavy tank with a battle rating of 2.3 (AB/RB/SB). It was introduced in Update 1.75 "La Résistance" as a pack vehicle and eventually discontinued from the store, but was later reintroduced for War Thunder's 7th anniversary as a premium purchasable in-game for 1,300 Golden Eagles and through the Warbonds mechanic. Its most noticeable features from its predecessor (B1 bis) are an increased horizontal traverse for the hull gun, thicker armour and an extra crew member.

AMX-13 (SS.11)
The AMX-13 (SS.11) is a premium rank IV French light tank with a battle rating of 6.7 (AB/RB/SB). It was introduced in Update 1.75 "La Résistance" as a bundle vehicle but was removed from the store after the 2018 Summer Sale. It was later reintroduced for War Thunder's 6th Anniversary as a premium purchasable for 7,480 Golden Eagles .
The only difference from the AMX-13 light tank series is the rack of four deadly SS.11 missiles in the oscillating turret front. Everything else from the two protruding radio antennas to the four smoke dischargers are identical to the original AMX-13 model.

AMX-13 (HOT)
The AMX-13 (HOT) is a Rank VI French light tank with a battle rating of 8.3 (AB/RB/SB). It was introduced in Update 1.75 "La Résistance".
At its current battle rating, the AMX-13 (HOT) can definitely do some serious damage, even to top-rank MBTs and (as of 1.81) helicopters too. The six HOT ATGMs are enough to penetrate almost any armour in the game on direct hit, save for the M1 IP's turret cheeks (which it doesn't have to face), and the T-64B's upper glacis (with ERA in place at high angle). All six missiles can be fired in short succession, although only the one fired last can be controlled.
This makes it a viable tank destroyer, but unlike any of the MBTs, it cannot take a hit and survive. Even certain machine guns and aircraft cannons are capable of killing it easily. Use your spotting ability to alert your team to enemies, and try and get an ATGM in a critical spot, like crew or ammo. ATGM have problems breaching fuel tanks, engines and radiators, so avoid hitting those with missiles.
Just remember: You only have six ATGMs, after that, you are using a conventional gun, firing solid shot AP, which technically can ammo rack tanks like T-64 and T-80 from the side, but it's not a guaranteed kill.

AMX-50 Surblindé
The AMX-50 Surblindé is a gift rank V French heavy tank with a battle rating of 8.0 (AB/RB/SB). It was introduced in Update 1.89 "Imperial Navy" and has the distinction of being the first gift vehicle of the French tech trees. Member of the French AMX-50 tanks family, it is very similar to the AMX-50 Surbaissé. Compared to it, it is lower, has a more protected turret armour and has a 20mm MG 151 canon at the top, which is very efficient against aircraft and lightly armoured targets. Anyway, it is also heavier and hasn't smoke grenades launchers compared to the Surbaissé.
It could be obtained as the highest reward of the first season "Recon under Fire" of the World War mode, but can also be bought on the War Thunder Market.


AMX-30 (1972)
The AMX-30 (1972) is a rank V French medium tank with a battle rating of 7.7 (AB/RB/SB). This medium tank was introduced in Update 1.75 "La Résistance". The AMX-30 is the first tank to use France's very own 105mm gun, the CN-105-F1 designed in tandem with the Obus G spin stabilized High Explosive Anti-Tank round; a 12.7mm M2HB heavy machine gun for a co-axial, and a 7.62 mm machine gun on the cupola.

AMX-30B2
The AMX-30B2 is a Rank VI French medium tank with a battle rating of 8.3 (AB/RB/SB). It was introduced in Update 1.75 "La Résistance". This vehicle has the particularity to throw the usual 7.62 or .50 co-axial MG away for a powerful rapid firing 20 mm autocanon that can be elevated up to 40° that fires HEIT and APIT projectiles with a penetration up to 40 mm at close range and against straight armor.

AMX-30B2 BRENUS
The AMX-30B2 BRENUS is a Rank VI French medium tank with a battle rating of 8.7 (AB/RB/SB). It was introduced in Update 1.77 "Advancing Storm". The AMX-30B2 BRENUS, or Brennus in some sources, was a modernized French MBT which saw combat in the Gulf War.

AMX-32
The AMX-32 is a rank VI French medium tank with a battle rating of 9.3 (AB/RB/SB). It was introduced in Update 1.97 "Viking Fury". An improved version of the AMX-30, it gets an upgraded gun, an upgraded engine, and spaced armour giving additional protection and advantages on the battlefield. There were several versions of the AMX-32 developed. This version represents the 1981 120 mm armed version with the retrofit of thermal imagery equipment which was proposed in 1985.

AMX-40
The AMX-40 is a rank VI French medium tank with a battle rating of 9.7 (AB/RB/SB). It was introduced in Update 1.79 "Project X".
The AMX 40 represents a massive shift in the French tank tree, with the addition of a stabilizer, whereas all other vehicles, with the exception of the American vehicles (Sherman M4A1, Jumbo.) have no actual stabilizer. Many players might find themselves hesitating to fire a shot as soon as a target is seen because there is usually time to think before the gun is stabilized, but at this rank, French players might find themselves having a hard time shooting before their enemy.

SWEDEN

Strv 81 (RB 52)
The Strv 81 (RB 52) (full name: Stridsvagn 81 (RB 52)) is a premium rank IV Swedish medium tank with a battle rating of 7.0 (AB/RB/SB). It was introduced during Update "Raining Fire" in the 8th Anniversary Sale as a replacement for the British version of the vehicle.

Strf 9040 BILL
The Stridsfordon 9040 BILL is a rank VI Swedish light tank with a battle rating of 9.7 (AB/RB/SB). It was introduced in Update "Starfighters". The Strf 9056, like the two other Strf 9040 variants (The Strf 90C and Lvkv 90C), is armed with a Bofors L/70 40 mm anti-aircraft gun repurposed as an omnipurpose (anti-tank, anti-aircraft) gun. It is also armed with Rbs 56 ATGM's.

Conclusion

If you want a nice secondary gun I suggest you look at the US or French tech-tree.

The US is great at providing hull mounted cannons, while the French provide the powerful 20 mm 20F2 automatic cannon for most of their late-war/cold war tanks.

Russia has some nice landships, likewise you can find some similar tanks with the early French tech-tree.

Sweden, Italy and China either never developed or thought of the idea of using several larger armaments on their tanks. Italy and Sweden have clear, tought out playstyles, that are very well represented true their individual tech-trees.

A honorable mention for me is the Chi-Ri II. Its design was far ahead of its time (designed in 1943) the tanks armor was relevant at the time, its armament surpassed those of the allies and it could theoretically perform far better than the Sherman M4. It's also equipped with an auto loader, providing three shots on target, in a short period of time. The hull mounted 37 MM gun would have been a great boon when fighting in dense urban areas, and could even pen the Russian T-34 from the sides.
