=== Survivability and armour ===
−
<!-- ''Examine the survivability of the helicopter. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical systems.'' -->
+
<!-- ''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the 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.

The AH-1S is an armoured attack helicopter offering protection to the crew and engine:

=== Mobility ===
 +
<!-- ''Write about the mobility of the ground vehicle. Estimate the specific power and manoeuvrability, as well as the maximum speed forwards and backwards.'' -->
  
−
* Composite boron carbide seat enclosures, for both of the crew, with a thickness of 20 mm.
+
{{tankMobility|abMinHp=190|rbMinHp=133}}
−
* A steel seat, which offers a thickness of 12 mm for the pilot only.
 
−
* Steel plate covers, offering 12 mm of thickness over the turboshaft engine.
 
  
−
The AH-1S compensates with its small and nimble size compared to the [[Mi-24 (Family)|Mi-24 Hinds]] which are incredibly well armoured but are huge and slow in comparison. However, the AH-1S does not protect all of its critical components, such as the fuel tanks, transmission, propeller shaft, and control surfaces, with armour plating, nor does it have armoured glass installed around the cockpit.
+
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 '''''{{PAGENAME}}''''' is armed with:
+
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.

When playing the AH-1S, select the helipad which is in the ideal tactical location for your playstyle. Climb to around 1,500 meters, find a target, then descend on to them. For optimal effectiveness, it is important that you engage them from the rear or the side. As pilots primarily scan in front of themselves for targets, attacking from behind will give you the advantage of not being seen. When shadowing the target, approach as fast as possible to close the gap to within TOW range. After slowing, engage the sight stabilizer and fire the TOW missile and guide it to the target.
+
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.
−
 
 
−
If the target tries to evade, keep the missile on the target and adjust to counter any manoeuvres your adversary may attempt.
 
−
 
 
−
Perhaps most importantly, if out of TOW range, the missile will self-detonate and could give your position away, if your adversary is attentive and sees the explosion.
 
−
 
 
−
{{Notice|Remember you only have around one and a half miles before the missiles will detonate by themselves, you can only select to carry either 4 or 8 BGM-71 TOW missiles.|!}}
 
−
 
 
−
After gaining experience while playing with the BGM-71 missiles, you will be able to determine when you are within range based on that experience. This also applies to any other type of missile in the game too.
 
−
 
 
−
When engaging in close quarters combat with other helicopters, the biggest threats are air to air missiles- The AH-1S does not offer any protection against them with countermeasures such as flairs or IRCM. This means you need to stay alert, active & on the lookout for fast moving dots. If you see a small fast dot heading towards you, make very sharp abrupt turns, change height at the same time while turning and rolling.

{{Notice|You may even be able to shoot down missiles with the installed 20 mm triple rotary M197 cannon.|!}}
 
−
 
 
−
When engaging other helicopters, the triple barrel rotary cannon makes short work of any adversary. Make sure to load it with the air target belt, aim for critical elements of the rival helicopters such as cockpit, engine and fuel tanks. If you have equipped your helicopter with the additional twin M134 miniguns, bring your target in front of you and open fire. They will obliterate the target and send a flaming wreck to the ground. The fast fire rate will chew through ammo at a rapid rate, but when fully loaded have 3,000 rounds in total. That's 1,500 rounds per mini gun, in addition to the 750 cannon rounds for the M197, potentially up to 3,750 rounds total!

====Ground forces====
 
−
 
 
−
Playing the AH-1S in ground forces, it is recommended to load up the 8 x BGM-71 TOW-2 missiles + 38 x FFAR Mighty Mouse missiles. The BG-71 will give you the penetration at range in order to terminate tankers and with safety from the anti-aircraft missile equipped anti-air vehicles. It is a wise tactic that anti-aircraft missile equipped anti-air vehicles to be terminated first. Then once terminated, move into the battlefield and dominate the tanks with the 38 x FFAR Mighty Mouse missiles, which can cause a lot of damage and could potentially terminate up to 38 tanks with well-placed shots.
 
−
 
 
−
The ideal tactic is to utilize the helicopter and the terrain. Such as maps which have forests and lots of tree lines, stay low over the trees and select your targets based on the threat to yourself first, then the impact to the team.
 
−
 
 
−
For example, if you have seen no enemy SPAA vehicles or other helicopters, climb in height, hover, then fire one or two missiles. Then quickly break off the hover and move to another part of the map, this way it allows you to stay undetected, remain stealthy and become a major threat to the enemy team.
 
−
 
 
−
Handling radar and surface-to-air missiles, when an enemy missile equipped SPAA is achieving a lock on, you will be notified with red arrows on the screen saying radar. To break the lock start rolling, gaining speed and the arrows will go away. If you are not successful, keep a close watch around the helicopter. At this, you will see white smoke coming from the ground, make very sharp abrupt turns. Change height at the same time while turning and rolling to avoid the missile.

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.

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.

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.

Description

GarageImage Ikv 103.jpg


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.

Mobility

Game Mode Max Speed (km/h) Weight (tons) Engine power (horsepower) Power-to-weight ratio (hp/ton)
Forward Reverse Stock Upgraded Stock Upgraded
Arcade 58 12 8.8 190 286 21.59 32.5
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.

Pros and cons

Pros:

  • Excellent HEAT round for its rank, able to penetrate the upper glacis plate of the Tiger II
  • Above average mobility, able to secure crucial positions or even flank the enemy
  • Neutral steering
  • Able to hull-break light vehicles
  • Small silhouette
  • Incredible gun depression

Cons:

  • Poor armour, sides able to be penetrated by heavy machine guns, and even rifle-calibre bullets behind the tracks
  • Has hull-break
  • No MG to destroy light fences that can fuse your HEAT shells
  • Slow gun traverse, makes aiming in CQB or moving target harder
  • Vehicle reverses slightly when firing, forcing you to reacquire range of target after every shot
