Description
The Stormartillerivagn 20.12.48 is a gift rank III Swedish tank destroyer with a battle rating of 3.7 (AB/RB/SB). It was introduced in Update 1.95 "Northern Wind".
General info
Survivability and armour
The Sav 20.12.48 is very lightly armoured, sacrificing protection for mobility. The highly sloped glacis is 30 mm thick, and can sometimes cause rounds to ricochet, but it is not reliable in any sense of the word. The rest of the tank is vulnerable to even heavy machine guns, and the open top is extremely vulnerable to strafing aircraft.
Mobility

|---|---|---|---|---|---|---|---|
| Forward | Reverse | Stock | Upgraded | Stock | Upgraded | ||
| Arcade | 53 | 21 | 20 | 568 | 763 | 28.4 | 38.15 |
| Realistic | 49 | 19 | 354 | 400 | 17.7 | 20 | |
The Sav 20.12.48 has excellent mobility for a tank destroyer, featuring a high top speed as well as a fast reverse. The result is a highly agile tank destroyer that is capable of taking positions or retreating into cover quickly.

Armaments
Main armament
The 120 mm automatkanon is a potentially devastating weapon. It is fitted with an automatic loader that is fed by a six-round clip, for a total of seven shots ready to go once fully loaded (including one in the gun barrel). The autoloader has an extremely fast reload of only 1.2 s, allowing the Sav 20.12.48 to engage up to seven targets in under 10 s. Once the clip has been expended, a new round must be loaded into the clip before the autoloader may be cycled and the gun made ready to fire. However, this process only takes a few seconds. The gun also has a good amount of gun depression, allowing the Sav 20.12.48 to abuse hills when combined with the high reverse speed.
The primary shell is the hpgr m/50 APCBC round. With nearly 1 kg of explosive filler, it is extremely deadly and almost guaranteed to one-shot anything if it penetrates the crew compartment. Its penetration is quite respectable; although not quite enough to frontally penetrate everything the Sav 20.12.48 can encounter, it has more than enough penetration to kill most tanks from the side. It has a relatively low muzzle velocity, however, and is thus hard to hit with at long range.

Usage in battles
The combination of high mobility, powerful explosive filler APCBC shells, and autoloader make the Sav 20.12.48 an extremely dangerous tank destroyer to face. It is fast enough to quickly setup ambush positions near where the enemy team is likely to pass by, and a careless team can quickly find itself losing up to seven tanks in less than 10 s to the Sav 20.12.48 lying in ambush. Ideally, the Sav 20.12.48 would also be in a hull down position, where most of the tank can be hidden since the gun is mounted near the top of the vehicle and the high reverse speed allows it to back into cover quickly.
The vehicle itself is very fragile, however, and if it is caught out of position it is very easily destroyed. It is also very vulnerable to aircraft due to the open top, and has no means of defending itself from aircraft.
It can also be very tempting to fire off all seven rounds at once, but as with all autoloaders, trigger discipline is a very important skill to develop in order to use the vehicle to its full potential.
Pros and cons
Pros:
- Highly lethal APCBC explosive filler shells
- Good mobility and high reverse speed
- Can fire seven rounds within 9 s using the autoloader
- Excellent gun depression
- Small silhouette, especially when hull down
Cons:
- Very thin armour
- Open crew compartment, highly vulnerable to strafing aircraft
- Must reload at least one round into clip before the gun can be fired
- Low shell velocity
- Sustained firing decreases accuracy
- Struggles to penetrate heavy tanks like the KV-1 and Churchill series of tanks, even at close range
History
Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
