Description

The Infanterikanonvagn 91 is a rank V Swedish light tank with a battle rating of 7.3 (AB) and 8.0 (RB/SB). It was introduced in Update 1.97 "Viking Fury".

Besides its drawbacks, it is overall an excellent light tank, notably because of it's excellent HEAT shell but also because of its amphibious capabilities.

General info

Survivability and armour

As one would expect from a light tank, the Ikv 91 is very weakly armored, but still is much more survivable than its predecessor the U-SH-405. The armor, both on the front and sides, protects from small arms (like British 7.92mms for example) and most splash damage. However, while the front hull also protects against .50 cals, the turret can be penetrated, which can quickly lead to death as 3 out of the 4 crew members are in the turret.

Its 4 crew member means it can lose 2 crew members before being taken out of combat, although it is worth noting that 3 of them are in the turret, meaning that a well-placed shot to the turret can kill instantly. The engine and transmission are located in the rear hull, meaning that shots to the front hull are unlikely to destroy them, and shots to the rear hull are unlikely to kill as the engine and transmission will absorb most of the damage - while the crew is not close enough to be hurt by the shrapnel.

Mobility

While the Ikv 91 is slower than wheeled light tanks on road (58km/h|36mph in RB/SB, 65km/h|40mph in AB), it has very good mobility off-road and a good power-to-weight ratio (20.2hp/t in RB/SB, 38.6hp/t in AB), overall allowing it to take positions ahead of the enemy main forces and to relocate quickly.

Armaments

Main armament

The Ikv 91 has for main armament a 90mm gun able to use two shells: HEAT-FS and HE. All shells are unlocked from the beginning, even the excellent HEAT-FS with 400mm of penetration and a whole 655 grams TNT equivalent of explosive mass. The turret traverse speed is not the best for a light tank (18.8°/s in RB/SB and 35.4°/s in AB while the American M41A1 Walker Bulldog gets 33.3°/s in RB/SB and 63.7°/s in AB) but is above average at its BR and usually enough. The same goes for targeting the gun up or down.

The reload speed is faster than average, but quite a few tanks reload faster at this BR, notably light tanks (the BMP-1 for example). The reload speed is also dependent on the first-stage ammo stowage, meaning that it will get slower should one run out of first-stage ammo.

A maximum of 59 shells for the main gun can be carried, although the high-effectiveness of the HEAT shells gives the possibility for players to only carry a fraction of that and still be able to take out several targets in one run. The first-stage ammo stowage is comprised of 16 shells all located next to the loader, the next 25 shells are located between the loader and the engine, and the last 18 shells are located in the front hull next to the driver.

Going with 16 shells is usually the best bet if one wants to lower the chances of getting its ammunition detonated as much as possible as they're all going to be at the same spot. Going with 20-25 shells is not much more dangerous as the 25 shells following the first-stage ammo are all located next to the engine, where other players do not usually shoot.

The slow speed of both HEAT-FS and HE is offset by the laser rangefinder, a rare feature for this BR, making the Ikv 91 effective at long-range engagements too.

Machine guns

The Ikv 91 comes with two 8mm machine guns: A turret-mounted machine-gun and a coaxial machine-gun next to the main gun. The machine-guns have a relatively slow fire-rate but are still effective at taking out exposed crew members of enemy vehicles.

Usage in battles

Thanks to its excellent HEAT-FS shell, the Ikv 91 can engage any target, even when up-tiered. However, a margin of caution is still needed when going against tanks that have .50 cals, as .50 cals can go through the sides and turret to then kill the gunner, loader and commander. The good mobility makes it able to go from one objective to another very quickly, and its amphibious ability gives another way to flank and makes it able to reach positions otherwise inaccessible. The laser rangefinder also gives it the possibility to quickly make accurate long-range shots. The -10° depression also allows it to take firing positions that some other tanks cannot (particularly the Russians that usually only have -5°).

Overall, the Ikv 91 can be played at mostly any range and can outmanoeuvre most of the tanks it encounters. Although it cannot attract too much attention as its particularly weak to aircraft, but is able to use smoke shells to hide in cases like these.

Pros and cons

Pros:

• Solid mobility, especially off-road
• Amphibious
• Excellent HEAT-FS shell that is unlocked from the beginning
• Laser rangefinder, a feature that almost no other tanks get at this BR

Cons:

• The armor does not protect against .50 cals everywhere, notably the turret
• No stabilizer
• No night-vision

History

The Ikv 91, short for Infanterikanonvagn 91 (infantry cannon wagon 91), was a high mobility assault gun that was developed to meet the operational requirements of the Swedish Army. It was designed and manufactured by Hägglund and Söner (now Hägglunds Vehicle AB) and employed common components with the Pbv 302 armoured personnel carrier series. The first prototypes of the Ikv 91 were completed in 1969 with production running from 1975 until 1978. The total numbers manufactured were 212.

Historically, and unlike in War Thunder, the Ikv 91 came with a night vision device and a computerised fire-control system. It stayed in active duty until it was fully retired in the early 2000s, both for budget cuts and as newer designs like the Strf 90 could fulfil its role.

In 1983, a prototype variant of the Ikv 91 with a fully-stabilized 105mm gun was marketed for export, but was never used by Sweden itself.
