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.

In Rank V, the M47 Patton does not have suitable armour against the numerous 88 mm, 100 mm, and 122 mm calibres running around the field. However, it makes up for that with a potent 90 mm cannon with new ammunition able to fight back. Due to the armour thickness of the Rank V tanks, it is recommended to use the M47 Patton's speed to flank the enemy, then engage them on their sides to detonate their ammo racks or knock out the crew.

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 '''M47 Patton''' came about only a few years after its predecessor, the [[M46|M46 Patton]]. The basis of this design was the [[M26|M26 Pershing]], which was deemed insufficiently mobile for its role as a medium tank. The M46 was mainly the M26 Pershing with a new engine, transmission, and a redesigned 90 mm gun. While a good solution for the lacking M26 Pershing design, it was only considered a stopgap solution while the experimental ''T42 medium tank'' was being developed. However, the Korean War put a stop in that development due to an urgent need of tanks, so the T42 project, which would produce a completely new tank design, was put on hold.
+
* Able to hull-break light vehicles
 +
* Small silhouette
 +
* Incredible gun depression
  
An interim decision was made to mount the turret from the T42 onto the hull of the M46 Patton, this modified tank was designated the '''M47 Patton''' and entered production in 1951. A common nickname for the tank was the ''Patton II'', due to the same name as the M46 Patton, this was changed to ''Patton 47'' a few weeks later. The M47 Patton featured most of the armament seen from the M26 Pershing and M46 Patton, with a 90 mm gun and a coaxial and hull-mounted .30 cal machine gun, and a .50 cal machine gun on top of the turret. The M47 Patton has the distinction of being the last American tank with the hull-mounted machine gun on the bow. The new turret required the hull to be redesigned with a larger turret ring and had a "needle-nose" design with the turret mantlet heavily sloped towards the cannon, the design's heavy sloping nature also helped improve protection. The turret also had a large protrusion at the back to act as storage. An M12 stereoscopic range finder was also mounted on a turret, which was difficult to use, but would appear in every American tank design from here on until the M1 Abrams design.
+
'''Cons:'''
  
Though technically a medium tank by the army standards, a new standardization in US Army tank designation on November 9, 1950, had the entire system changed from the weight of the tank to the calibre of the vehicle's gun. Therefore in the 1950s, the "Medium Tank M47 Patton" name was changed to '''90 mm Gun Tank M47 Patton'''. This designation would go on for future American tank designs. The M47 Patton began production in June 1951 before its standardization at the Detroit Tank Arsenal. Delays in the production schedule caused a long period of testing to occur until it was standardized in May 1952. Production ran until November 1953 with a total production number of more than 9,000 M47 Pattons between Detroit and Alco.

The M47 Patton came out only a year before the improved M48 Patton. Because of this, the M47 was declared a "limited standard" in American service, and those still in American hands were replaced by the M48 Patton tanks. It was declared obsolete by 1957 and were only retained by infantry divisions until replaced by anti-tank missiles in the 1960s. The M47 Patton was given out in large numbers to a number of countries in NATO and SEATO, such as Pakistan, Jordan, Turkey, Iran, Croatia, France, West Germany, and Spain. The M47 Patton would see service in combat in both Indo-Pakistani Wars, the Six Day War, the Iran-Iraq war, the Invasion of Cyprus, and the Croatian War of Independence. Today, they are still being used in Spain as armour recovery vehicles in artillery and infantry units.

The M47 Pattons were promising new designs developed from the M46 Pattons to improve its combat capabilities with a newer turret. However, it did not serve much in America due to the M48 Patton development, which was a completely new design and had nearly no identical parts with its predecessor. It served very well in other countries as their primary armour forces, but those left in the states were used as targets in firing ranges, mainly for training or as tests for future anti-tank developments. In the 1970s, one was tested against the [[M60|M60 Main Battle Tank]], the successor to the M48 Patton, and its 105 mm L7 gun. The HEAT round fired from the gun penetrated the frontal armour of the M47 Patton with relative ease, armour which was considered superb at its time of introduction. The test went on with many M47 tanks and would prove that conventional steel armour in tank warfare was becoming obsolete in the face of new tank ammo.

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 M47 Patton II medium tank, released in the US beginning in June 1951 by the Detroit Tank Arsenal and the American Locomotive Co., was a modernized version of the M46 Patton.
 
  
The M47's frontal hull sheets were more sloped, while infrared viewfinders and a heater were added for the crew. The construction for the cast turret was also updated: it took a step forward from the M46, though the builders reduced its interior space in order to add a cupola and reloader's hatch in its overhangs. As a result, indentations were made that proved excellent at catching shells. That error was rectified for the M48 by making the turret fully domed, similar to the Soviet T-54. The tank's armament was reinforced by modernizing the 90 mm cannon, resulting in an initial velocity of over 900 m/s. The M47 hull also differed from the M46: its front section was more streamlined, while the fan hood between the driver and gunner disappeared. Engine power was added, though the tank's top speed remained the same (although the average terrain it encountered was somewhat higher).

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.
  
As a result, the M47 did not become standard for American tank construction, and it was quickly replaced in its limited role for the US Army (two divisions in West Germany) by the M48. However, it was actively distributed among NATO countries and other US-dependent allies, resulting in total production of 8,676 units.
+
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.
 
 
The M47 Patton II was part of the West German, Austrian, French, Italian, Belgian, Spanish, Jordanian, Japanese, and Turkish armies.

Description

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.

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 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.

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.
