Description
The Stormartillerivagn m/43 (1944) is a rank I Swedish tank destroyer with a battle rating of 1.7 (AB/RB/SB). It was introduced in Update 1.97 "Viking Fury".
General info
Survivability and armour
The Sav m/43 has up to 50 mm of armour in front, which is capable of deflecting some guns commonly encountered but is still vulnerable to larger calibres. It has better frontal protection than the Ikv 72, but is still rather lightly armoured from other angles. It should be noted that the engine deck is only 10 mm thick, and can be penetrated by aircraft heavy machine guns and cannon. The side armour is only 15 mm thick at most, and can also be penetrated quite easily by heavy machins guns and autocannon fire.
Due to the cramped crew compartment and scattered ammunition within the compartment, any penetration by a shell is likely to cause critical damage to multiple modules and/or crew members.

The Sav m/43 is based on the chassis of the Strv m/41 and thus has a similar level of mobility. It is considerably heavier, however, and thus correspondingly more sluggish. While the forward top speed is adequate, the reverse speed is quite poor, making it hard to retreat. It is also noticeably slower than the Ikv 72.

Armaments
Main armament
The Sav m/43 is armed with the 7,5 cm kan m/02, an older and weaker 75 mm field gun compared to that used in the Ikv 72. It has wider traverse arcs and higher maximum elevation, but less gun depression than the Ikv 72, though still quite good at -10 degrees. It starts off with the unremarkable slpprj m/40 uncapped AP shot, which is adequate against most opposition it may encounter but tends to suffer ricochets against sloped armour. However, once upgraded, the gun may fire the slpgr m/39 uncapped APHE shell and the slpprj m/40B APBC shot. The former round has a very lethal 260 g TNT filler but tends to ricochet more and has less penetration, while the latter has better penetration and ricochets less, and is thus more useful in uptiers. It is recommended to carry a mixture of both APHE and APBC unless the Sav m/43 is top tier, in which case the APHE alone is sufficient.

Usage in battles
The Sav m/43 (1944) is a more forgiving alternative to the Ikv 72. Like the Ikv 72, it performs best in a hull down position, as it can use the depression to present a steeper angle on the frontal armour to increase its effective armour thickness. It is somewhat less vulnerable than the Ikv 72, though it is still relatively weak armour from the sides, top and rear armour and is best considered to play this vehicle cautiously since it have slower manoueverbility to compared to the previously in the line Ikv 72.
The armour in its own and 1.0 battle is adequate enough to survive most blows with the frontal armour, but leaving its side and rear exposed to enemies will make a quick work of it, Hence its a good support role vehicle to help allied vehicles by either finish the enemies off or draw attention to itself with the frontal armour so the allied vehicles can finish it off. Against heavier armored vehicles or just vehicles with better guns such as M3 Lee and B1 ter its better to avoid direct confrontation and not fight on equal terms.
While the gun is quite adequate against most enemies at its battle rating, it can be seen obsolete in up tiers where it will face opponent tanks with considerably more armour compared to tanks at 1.7. The gun might not be able to be efficent at 2.7 but it can still be do damage if doing ambushes and shooting from hills, using the angled armour and the depression of the gun to it's advantage. It can lock down areas and buy time for allied tanks to come to its aid doing flanking manouevers. Sav m/43 (1944) can also move around to flank heavier armoured vehicles getting on their side armour will give it a shot to penetrate and ability to disable the more armored tanks when frontal engagement is not a viable option.
Enemies worth noting:
M4A3 (105): The M4A3 (105) is a dangerous vehicle for the SAV m/43 (1944) to encounter, angled armour making the shells of the Kan m/02 next to unusable against its angled frontal armour. It also got a gun with HEAT shell that will make quick work of the Sav's armour and most likely detonate the ammunition or knock out the crew if gets in a good shot on the Sav. Best to stay away or ambush it where it shows off it's less armoured and flat side armour.
B1 ter: The B1 Ter got armour which got enough efficency to ignore the penetration capability of the SAV m/43's rounds, lacking in firepower compared to vehicles like M4A3 (105) or M3 Lee, it can still do quite the damage with the 47mm gun in the turret. Best way to eliminate this type of target is to either hit the less armored turret or get a hit in the flat armored rear.
M3 Lee: Similar to M4A3 (105) the M3 Lee's armour can prove to be quite resilliant against the SAV m/43 (1944)'s shells forcing it to avoid the direct confrontation with the M3 Lee. Lee is not just well angled armoured medium tank, it also got a 75mm M2 anti-tank gun and a 37mm M5 in a turret which can prove to be efficent against the SAV m/43's armour. Making it a lethal opponent to face aswell, where best chance is to catch one off guard on the side or rear and attack the weaker side or rear armour.
Pros and cons
Pros:
- Decent frontal armour in a downtier
- Lethal APHE round, able to frontally penetrate and one-shot almost all tank it faces
- Wide gun traverse arc and good gun depression allows turret to acquire target without requiring constant adjustment of the hull
- Decent top speed
- Has smoke shells which can "lock down" an enemy area by shooting smoke shells there
- Adequate reload speed
- Has small silhouette
Cons:
- Low penetration works poorly against heavy targets such as M4A3(105), B1 ter
- Very thin side, rear, and roof armour
- Very slow shell velocity, leading and shooting fast tanks (eg. M22, BT-5) is hard
- Curved shell trajectory demands precise aiming at long range
- Shells have weak penetration past 500m
- Mediocre mobility and poor reverse speed
History
In March of 1940, Sweden ordered about 90 TNH tanks (known as the Panzer 38(t) in German service) from ČDK, but Germany, which had occupied Poland in 1938, confiscated the tanks for its own use as the Panzer 38(t) Ausf. S. Sweden still needed the light tanks, and after negotiations the Swedish manufacturer Scania-Vabis was allowed to produce them under license, and compensation for the lost tanks. Sweden ordered 116 Strv M/41 SI in June, 1941, and in June of 1942 Sweden ordered 122 Strv M/41 SII. The last 18 Strv M/41 SII were built as the Sav M/43 in 1944. Another 18 Sav M/43 were purpose-built afterwards. The Sav M/43 was a casemate assault gun made by removing the turret of the Strv M/41, and adding a casemate superstructure, initially housing a 75 mm gun. The 75 mm gun was replaced by a 105 mm M/44 Bofors cannon. The Sav M/43 served in artillery units until 1951, when they were given to armored units instead. They served until 1973.
Devblog
In 1942, Sweden began developing a new SPG built on a modified chassis from the Czech LT vz.38, better known as the Pz.38(t) in the German army. This new SPG was supposed to be equipped with the 75mm L/31 cannon that was already in production. By autumn of 1942, a wooden model of the planned vehicle had been created and, after a number of improvements, the project advanced to manufacturing prototypes. Exactly one year later, in October of 1943, testing began. The SPG passed with flying colours and hit assembly lines under the designation Sav m/43 (short for "Stormartillerivagn", Swedish for "assault artillery carriage"). A little later, a version with a 105mm gun came out, and, by the end of 1946, all m/43 SPGs had been re-equipped with this new cannon. The Swedish army had used this SPG until the early 70's. From the moment it entered military service until the end of the Second World War in Europe, the Sav m/43 vehicles were grouped by the Norwegian border and then assigned to infantry units as fire-support vehicles when the army was reorganised.
