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.

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.


Main armament

Main article: automatkanon (120 mm)
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.
