The Infanterikanonvagn 73was an infantry tank that originated during the 1950s. However the design dates back to the Lago I, an export project that was meant to be developed as a tank for Hungary in the 1930s. However, since Hungary withdrew, the Lago I later became the Strv m/42, one of the versions of that tank was the Strv /42 EH, which was retired in the 1950s after the introduction of the Strv 81. Thus, the tank was remodelled and repurposed as an infantry support tank, designated Ikv 73. The tank remained largely the same, although the turret was modified to fit a new roof mounted machine gun.
Introduced in Update "Starfighters" as a reward for the 2020 Operation S.U.M.M.E.R. event, the Infanterikanonvagn 73 has a similar playstyle as the Strv m/42 EH except the hull machine gun has been replaced with a roof-mounted MG, giving it a better chance to destroy aircraft and engage open-top vehicles. The tank has a decent mobility, although with a slow reverse speed, it will be faster than most medium tanks. However the main problem is the low penetration of the gun, the APHE shell is not the most reliable against tanks like the KV-1 and T-34, although if it does penetrate it has a very good amount of explosive filler, and in most cases it would overpressure the interior, specially if the tank is hit in the middle of the crew compartment.
Survivability and armour
Armour protection on the Ikv 73 is average for its tier. While it is 55 mm thick, it is practically vertical. Angling your armour will not help, as the sides are only 30 mm in thickness. The turret armour is pretty much identical to that of the hull. The crew is very tightly packed, so a penetrating shot to the turret or hull is a guaranteed destruction.
Although the best course of action in an Ikv 73 is to remain undetected, there will be times when taking a hit or two will be inevitable. In such a scenario, angle slightly towards the enemy with your front right corner (the one opposite the driver) and try to bait a shot to your right turret cheek (the one with the coaxial MGs). Early HEAT and HE projectiles, as well as the spalling from weaker APHE and Soviet shrapnel rounds, will likely be absorbed by the machine guns. Solid shot will be almost guaranteed to penetrate, but will only knock out the commander and machine gunner. Most shots to the rear engine deck will likely bounce due to the extreme sloping.

Mobility of the Ikv 73 is good; about the same as that of the Shermans or earlier Panzers. The tank swiftly accelerates to its top speed of 42 km/h (26 mph), and stops just as easily (though the tank tends to "drift" slightly when stopping mid-turn). The tank reverses at 5 km/h. The suspension damping allows for firing immediately after coming to a stop from full speed, though it is not powerful enough to allow for accurate fire while on the move. The Ikv 73 lacks neutral steering, but still turns about as quickly as its contemporaries.

Usage in battles
Ikv 73 has a similar playstyle as the Strv m/42 EH except the hull machine gun has been replaced with a pintle machine gun on the turret, giving it a better chance to fend off aircraft and defend against open-top vehicles like the ZiS-30 and CCKW 353 AA.
Ikv 73 shares the same Kan m/41 as the Strv m/42, so it shares the same performance where it's decent enough at its own battle rating, but will struggle in uptiers. The gun will struggle against T-34, M4 Sherman and heavier tanks like KV-1 in direct confrontation where it lacks penetration against the sloped and angled armour.
The armour of Ikv 73 is better than that of Lago I and similar to the Strv m/42 EH, giving it better survivability than the Lago I. The change of the Ikv 73 compared to the Strv m/42 EH, where the hull machine gun was replaced with more armour, gives the hull slightly better survivability against smaller guns than, for example, M4s, T-34s, or Pz.IVs
It still has the same characteristics as the Strv m/42, being heavier than the earlier Lago I with the added weight from more armour. However, mobility is still pretty good despite the increased armour and weight due to an improved engine being installed. Due to this edge in mobility, it can get to the locations needed to be able to perform ambushes from behind hills and cliffs. However, do note that the Ikv 73 retains a slow reverse speed that causes problems when having to reverse into a better position or go back into hiding after firing.
Enemies to note:
- T-34: T-34s have angled armour where the Ikv 73's gun might not be able to penetrate the frontal hull armour and they have a gun which can pose a serious threat to the Ikv 73. Ikv 73 has to be careful about where to aim at these kinds of targets.
- M4 Sherman: M4s angled or sloped armour can cause similar trouble as the T-34's armour, but Shermans have a thicker armoured plate giving it more serious problems to penetrate frontally so tactical thinking is required to deal with this type of target.
- KV-1 KV-1s are targets where the gun is seriously lacking in penetration capabilities to do any damage to KV-1. Only a well-placed shot at one of its weakpoints can do any damage. These types of heavily armoured vehicles will take time and skill to deal with in an Ikv 73.
- Panzer IV Panzer IVs are not serious threats in terms of armour like M4s, T-34s and KV-1s; but what the Panzer IV lacks in armour it compensates with a short or long 75 mm gun which can pose serious threat if they manage to hit the Ikv 73. The armour is no threat to the Ikv 73's gun so they are easy to deal with, but at distance the Panzer IV has the advantage over the Ikv 73.
