The '''{{Specs|name}}''' is a rank {{Specs|rank}} American heavy tank {{Battle-rating}}. 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 '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.97 "Viking Fury"]].
 
 
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-17E|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 can be used but cannot be angled sideways. 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.

The armour of the Ikv 103 is between 18.5 mm to 5 mm of thickness. This armour shouldn't be considered as survivable since every round you face will most likely penetrate and destroy most of what's left inside the tank. The thin side-armour has the occasional ability to result in overpenetration, but any frontal attack usually has enough force to activate most shell fuses. The tank is also incredibly weak against chemical rounds and aerial attacks due to the hull break featured on the vehicle. It is heavily recommended to avoid any form of damage since even artillery fire has the possibility of guaranteed destruction. Due to this low survivability, taking the maximum amount of ammunition isn't something to frown upon. Thanks to the short length of the round, as well as compact storage, ammunition explosions are quite rare.
If necessary use a visual template to indicate the most secure and weak zones of the armour.-->

'''Notes:'''
 
 
 
* Suspension wheels are 15 mm thick while tracks are 17 mm thick.
 
* Frontal armour plate is unevenly curved for better ricochet chances and efficient armour thickness.
 
* Side skirts are 25 mm thick rolled homogeneous armour and will trigger fuses on APHE projectiles. In most cases, APHE shells set off before reaching the main hull and destroying the ammo stack beneath. Still, both skirts and hull are not sturdy enough to withstand a regular AP shell.

The Ikv 103 sports a good engine with a fairly high RPM giving it a lot of torque for climbing a lot of obstacles and average terrain. Although the top speed never exceeds 50 km/h, the Ikv 103 cruises comfortably around 40-45 km/h on a straight line and 25-35 km/h on uneven terrain, depending on the driving level and modules unlocked, no matter the surface below it. The vehicle finds no issue traversing snowy and sandy terrain thanks to the low weight and good track surface, but struggles in deep waters due to the low chassis it sports. The reverse rate of the Ikv 103 is also quite good at 11 km/h. Even if this speed can't hold a candle to the regular speed the 103 has, the reverse rate is still enough to safely peek over hills and reverse back into cover before getting fired upon.

The Ikv 103 is outfitted with a 105 mm cannon firing heavy shells with a reload of 10-13 seconds depending on crew qualifications. This cannon is unusually short for its calibre, firing heavy shells with low-velocity. Although the early psgr m/49 lacks significant penetration and post-penetration damage, the later slpsgr m/65 HEAT-FS round packs up to 400 mm of penetration, easily penetrating anything it sees with devastating results. This later shell features a higher velocity than the previous round, as well as more explosive filler making the post-penetration much deadlier than before. The gun is aimed manually without the help of electrical equipment, resulting in a slow traverse rate. At maximum, the gun traverses at 8° per second, resulting in many deaths at closer ranges. This makes the gun most effective at medium ranges, where the traverse is ideal, and the shell velocity isn't crucial. It should be noted that the incredible gun depression allows the Ikv 103 to fire from extreme angles allowing it to safely engage targets without the risk of overexposing the tank, something which becomes incredibly useful to increase the vehicles survivability.

The Ikv 103 is a nimble vehicle with a small silhouette compared to its peers. The lightweight and powerful gun set it apart from other vehicles at the battle rating. The general playstyle can be compared to the Jpz 4-5 found in the German tech tree. This playstyle is a more aggressive spin on tank destroying than usual, where the vehicle has to make use of positioning rather than frontal survivability. The Ikv 103 can't use common sniping locations very effectively since any form of enemy retaliation will destroy the vehicle completely. Instead, the 103 needs to drive full speed to various locations where enemies are unlikely to expect danger. Although this playstyle requires a lot of map knowledge, the reward is quite high for a successful flank, thanks to the devastating cannon the Ikv 103 carries. Thanks to the light vehicle weight and strong engine, the Ikv 103 is also able to climb a lot of obstacles, something that helps a lot when fighting on bad terrain. However, maps that lack terrain entirely cripple the 103's performance quite significantly, since the tank cannot hide, resulting in a lot of face-to-face engagements, which the Ikv 103 almost always lose.
The M6A1 is at first a powerful machine with a 76 mm gun able to penetrate the front of most Rank III tanks. Once, bought make sure to stay behind cover as much as possible as one good hit can knock out the 76 mm gun. Another note is that with all multi-gun tanks, the secondary gun should be fired separately to maximize the efficiency of the shells. Since the tank is at Rank III, beware of [[IS-1]]s,[[Panther D|Panther]]s, [[Tiger H1|Tiger]]s and [[M4A3E2|Jumbos]] as they can all easily penetrate the weak frontal armour. Make sure to keep the rear safe as the M6A1's engine is very large for a heavy and is likely to set fire on the first hit. The M6A1 is only as powerful as to how the player uses it to its advantages.

===Development===
 
When World War II broke out, limited development in the United States meant that the military possessed very few tanks and so development hastened and eventually gave them tanks such as the [[M3 Lee|M3 Lee]] and [[M4|M4 Sherman]]. On May 20, 1940, the US Army Ordinance Corps began to work on a 50-ton heavy tank for their army. Initially, it was going to have a multi-turret design, two turrets with the 75 mm gun and one secondary turret with a 37 mm gun with a coaxial machine gun, then one more with a 20 mm gun with coaxial. Plus, four .30 cal machine guns were to be put on ball mounts on the front glacis and rear corners of the hull. This project was approved on June 11, 1940, and moved on as the ''Heavy Tank T1''. However at the same time, similar concepts in Europe of heavy breakthrough tanks such as the Soviet [[T-35]] and the German [[Nb.Fz.|Neubaufahrzeug]] tanks were falling out of favour due to lack of combat effectiveness and unfavourable performance for their cost, and the US did the same in October so the design was changed.
 
 
 
The tank now had one turret with a 3-inch (76.2 mm) gun alongside a coaxial 37 mm gun. The turret housed three crew members and was powered by an electrical traverse system. The commander's cupola was copied from the M3 Lee, featuring a hatch with it sown machine gun. Two .50 cal machine guns now protruded from the bow mount (fired by bow gunner) and two .30 cal machine guns as well (fired by the driver). The entire tank held six crew members, the commander, gunner, driver, assistant driver, loader #1, and loader #2. While the construction of the vehicle was feasible, the engine was not enough to power the vehicle reliably due to heavy 57-ton weight.
 
 
 
In 1941 to 1942, three prototypes were constructed with the different transmission, one with electrical and the rest with a torque converter. The ones with the torque converters were designated the '''Heavy Tank M6''' and '''M6A1'''. The electrical transmission design designated '''M6A2''', was never approved by Ordinance, but was to be manufactured anyway. It was hoped that 115 of these tanks could be built for further testing and production started in December 1942 with design changes. The commander's cupola now featured a regular hatch rather than the machine gun one, which was removed along with one of the machine gun in the front hull. By the time the M6 was ready for production, the Army was moving forward and interest waned on these heavy tanks with the [[M4|M4 Sherman's]] performance in the war. The M6's armour was only slightly thicker than the Sherman's and the 3-inch gun didn't offer too much improvement over the 75 mm gun, plus it had a large profile and low ergonomics, not to mention mechanical issues.
 
 
 
===Production and cancellation===
 
In early 1942, the M6 production was set for 250 a month but was cut down in September from 5,000 to a mere 100 when manufacturing focus moved to planes. By the end of 1942, Sherman's performance in the war proved its role in the war was more adaptable than the M6 heavy tank while remaining cheaper and lighter for transportation and supplying. This caused the M6 production to lower even more to just 40, before being shut down. Though testing with a 90 mm gun found the M6 to be a good gun mount, the poor layout of the tank restricted it, and the project was shut down before further development could be made.
 
 
 
In August 1944, the Ordinance Corps planned to modify some of the M6 heavy tanks with more armour and heavier armament to breach fortified areas. These were to be the '''M6A2E1''' and weighed 77 tons with a 190 mm front armour and a 105 mm gun. Eisenhower rejected these as impractical and cancelled it. The M6 was found to be obsolete by December 1944 with only 40 units produced and never seeing combat service. They served as a propaganda piece during the war and were all scrapped after it except one, which is put on display at Aberdeen, Maryland at the United States Army Ordinance Museum. During development, the M6 turret was modified to become the turret for the [[M10 GMC|M10 Tank Destroyer]].
 
 
 
=== In-game description ===
 
"At the end of May 1940 the US infantry chief of staff responsible for armor put together requirements for future tanks in light of what was happening in Europe: the German army was relentlessly moving toward France and using armor with great success along the way. The Wehrmacht's use of new Pz.IV tanks with 75 mm guns instantaneously made the American tanks and their 37 mm cannons obsolete.
 
  
The new tank type had to be heavy (around 50 short tons), with 76 mm and 37 mm cannons arranged side-by-side in the turret. It had four machine guns (two heavy caliber and two rifle caliber), a Wright G-200 engine, a Hydromatic transmission, and a top speed of 25 mph. The green light was given for the construction of four prototypes in February 1941.
+
The [[Ikv 72|Infanterikanonvagn 72]] was a project started in 1949 by Sweden for an assault gun. The intended role of this vehicle was to support the infantry in the attack, replacing towed artillery guns. The design was to be small, and of light weight, around 6 tons. This was to reduce costs so a larger amount could be produced. The first prototype from Landsverk, completed in 1950, was armed only with three machine guns. This was insufficient, and it was re-armed with a 75 mm cannon, the same gun from the [[Strv m/42 EH|Strv m/42]]. It was a small, lightly armoured vehicle, with a casemate superstructure housing the 75 mm gun. It had a crew of 4, and it was open topped. Starting in 1956, the Ikv 72 was upgraded to the Ikv 102 standard. This upgrade added an armoured roof for the crew compartment and a 105 mm gun replaced the 75 mm gun. The Ikv 102, in turn, was upgraded to the Ikv 103 standard. The Ikv 103 featured an improved engine, the Volvo B42 engine. The air intake was moved to grills on the rear of the vehicle, instead of through the crew compartment.
  
The prototypes developed by the Baldwin Locomotive Works were designed with different transmissions and hulls in the interests of finding the best option for full-scale production. Two modifications at most were permitted, and on April 13, 1942, the T1E2 and T1E3 were standardized as the M6 and M6A1. The latter added a welded hull, Wright G-200 engine, and torque converter to the M6.

 +
In 1949, the procurement division of the Swedish army placed an order for the development of a light assault self-propelled gun to substitute the [[Sav m/43 (1946)|Sav m/43]] SPG. Three companies took on the work: AB Landsverk took on the development of the platform, Volvo was responsible for the powertrain, and Bofors for the armament. In fact, three versions of the vehicle for different purposes were planned at first: one with a 75 mm cannon, a machine-gun-equipped modification, and also a special one that was intended for the deployment of specific weaponry, such as flamethrowers and rocket launchers. Thus, a light (merely eight tonnes in all), tracked infantry-support vehicle was produced, with an open cabin and bulletproof armour.
  
Mass production was scheduled for November 1942, though a report by General Jacob Devers on December 7 indicated that the M6s would enjoy only limited tactical use due to their size. Moreover, two M4s equipped with 75 mm and 76 mm weapons could be built in place of two heavy tanks. As a result, the Armored Corps hurried to revoke the contract.
+
In 1952, a cannon-equipped version, under the designation the Ikv 72 (short for "infanterikanonvagn", meaning "cannon-equipped infantry-support vehicle" in Swedish), was put into service. A little later, the SPG's were re-equipped with 105 mm howitzers and the cabin was retrofitted with a roof, which could protect the crew from bullets and shrapnel. This modification received the designation Ikv 102. Meanwhile, the Swedish army ordered another series of the vehicle with an upgraded chassis to allow installation of a new air-cooled engine, while the gun and the armour remained the same as the Ikv 102's. This new version was designated Ikv 103. The Ikv 102 and 103 SPGs remained in use by the Swedish army until the mid-1970s, when they were replaced with the [[Ikv 91]] SPG.
 
 
Between 1942 and 1943 the Baldwin Locomotive Works ended up producing 12 M6 heavy tanks. They did not join the army or see combat."

The Infanterikanonvagn 103 is a rank III Swedish tank destroyer with a battle rating of 4.0 (AB/RB/SB). It was introduced in Update 1.97 "Viking Fury".

General info

Survivability and armour

The armour of the Ikv 103 is between 18.5 mm to 5 mm of thickness. This armour shouldn't be considered as survivable since every round you face will most likely penetrate and destroy most of what's left inside the tank. The thin side-armour has the occasional ability to result in overpenetration, but any frontal attack usually has enough force to activate most shell fuses. The tank is also incredibly weak against chemical rounds and aerial attacks due to the hull break featured on the vehicle. It is heavily recommended to avoid any form of damage since even artillery fire has the possibility of guaranteed destruction. Due to this low survivability, taking the maximum amount of ammunition isn't something to frown upon. Thanks to the short length of the round, as well as compact storage, ammunition explosions are quite rare.

Realistic 53 12 133 150 15.11 17.05

The Ikv 103 sports a good engine with a fairly high RPM giving it a lot of torque for climbing a lot of obstacles and average terrain. Although the top speed never exceeds 50 km/h, the Ikv 103 cruises comfortably around 40-45 km/h on a straight line and 25-35 km/h on uneven terrain, depending on the driving level and modules unlocked, no matter the surface below it. The vehicle finds no issue traversing snowy and sandy terrain thanks to the low weight and good track surface, but struggles in deep waters due to the low chassis it sports. The reverse rate of the Ikv 103 is also quite good at 11 km/h. Even if this speed can't hold a candle to the regular speed the 103 has, the reverse rate is still enough to safely peek over hills and reverse back into cover before getting fired upon.

Armaments

Main armament

Main article: kan Ikv (105 mm)

The Ikv 103 is outfitted with a 105 mm cannon firing heavy shells with a reload of 10-13 seconds depending on crew qualifications. This cannon is unusually short for its calibre, firing heavy shells with low-velocity. Although the early psgr m/49 lacks significant penetration and post-penetration damage, the later slpsgr m/65 HEAT-FS round packs up to 400 mm of penetration, easily penetrating anything it sees with devastating results. This later shell features a higher velocity than the previous round, as well as more explosive filler making the post-penetration much deadlier than before. The gun is aimed manually without the help of electrical equipment, resulting in a slow traverse rate. At maximum, the gun traverses at 8° per second, resulting in many deaths at closer ranges. This makes the gun most effective at medium ranges, where the traverse is ideal, and the shell velocity isn't crucial. It should be noted that the incredible gun depression allows the Ikv 103 to fire from extreme angles allowing it to safely engage targets without the risk of overexposing the tank, something which becomes incredibly useful to increase the vehicles survivability.

Usage in battles

The Ikv 103 is a nimble vehicle with a small silhouette compared to its peers. The lightweight and powerful gun set it apart from other vehicles at the battle rating. The general playstyle can be compared to the Jpz 4-5 found in the German tech tree. This playstyle is a more aggressive spin on tank destroying than usual, where the vehicle has to make use of positioning rather than frontal survivability. The Ikv 103 can't use common sniping locations very effectively since any form of enemy retaliation will destroy the vehicle completely. Instead, the 103 needs to drive full speed to various locations where enemies are unlikely to expect danger. Although this playstyle requires a lot of map knowledge, the reward is quite high for a successful flank, thanks to the devastating cannon the Ikv 103 carries. Thanks to the light vehicle weight and strong engine, the Ikv 103 is also able to climb a lot of obstacles, something that helps a lot when fighting on bad terrain. However, maps that lack terrain entirely cripple the 103's performance quite significantly, since the tank cannot hide, resulting in a lot of face-to-face engagements, which the Ikv 103 almost always lose.
