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 is a more forgiving alternative to the Ikv 72. Like the Ikv 72, it performs best in hull down positions, as it can use the depression to present a steeper angle on the frontal armour to increase its effective thickness. It is somewhat less vulnerable than the Ikv 72, though it is still very weakly armoured from the sides, top, and rear, and must be played accordingly. It is also rather less flexible than the Ikv 72 due to its poorer mobility.
While the gun is quite adequate against most enemies, it becomes obsolete in uptiers, where tanks with good armour such as the Medium Tank M3 and Matilda can be encountered. The armour on the Sav m/43 also becomes inadequate quite quickly in uptiers.

Pros and cons
Pros:
- Decent frontal armour
- Lethal APHE round
- Wide gun traverse arc and good gun depression
Cons:
- Low penetration for a 75 mm gun
- Very thin side, rear, and roof armour
- 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.
