The Stridsvagn 103С is a rank VI Swedish medium tank with a battle rating of 8.7 (AB/RB/SB). It was introduced in Update 1.97 "Viking Fury".

The Stridsvagn 103C is a final production variant of the S-tank family. This modification includes modern improvements in all areas, giving the tank access to increased mobility, survivability, and firepower.

General info

The Strv 103C is a Swedish MBT with a unique design compared to all other tanks of the same era. The S-tank, as it is more commonly known, makes use of the hull to direct fire at various targets. This feature requires the unique "Enable Hull aiming" key, which turns the tank from its regular cruising mode, into a fixed turret, capable of aiming wherever the player points their cursor. The reason the Strv 103C made use of hull-aimed weaponry becomes apparent when looking at the armour. The Strv 103C has armour sloped back more than 75 degrees, giving it strong frontal protection, with a high likelihood of causing enemy shells to ricochet. Another luxury a hull-fixed gun offers is the use of an automatic loading system. The Strv 103C can fire its main 105mm cannon every four seconds, no matter the amount of crewmen left. Paired with high mobility, and the Strv 103C becomes one of the most unique main-battle tanks in the game. With a bit of ingenuity and patience, the Strv 103C works at all ranges, in almost all conditions imaginable.

This isn't to say the Strv 103C is without flaws. The tank is incredibly vulnerable to flanking maneuvers, as the side and rear have a thickness of 30mm. It usually doesn't matter what kind of vehicle gets behind the Strv 103C, as even SPAA has no issues penetrating the tank. The gun is also filled with drawbacks, especially relating to the aiming. Due to hull-aiming relying on the ground below it, aiming becomes increasingly difficult on uneven terrain as the tank tries to compensate for things in the way. This results in shaky, and highly inaccurate aiming at longer ranges. The tracking is also bad, as the tank finds it difficult to adjust the speed at which it steers neutrally. This requires a Strv 103C tanker to wait for the target to cross its line of sight, instead of following it along its path. The armour is incredibly weak against APFSDS rounds and ATGM missiles. These usually have enough penetration to knock the tank out in a single blow, exploding the ammunition in the rear as a final touch. As these types of munitions are quite common at this tier, the Strv 103C can't rely on armour against most opponents on the battlefield. A positive is that weaker types of munitions usually can't reach the crew compartment, resulting in the Strv 103C surviving 3-5 shells before dying from engine fires.

Survivability and armour

External survivability

The Strv 103C is outfitted with incredible frontal protection. This strong impenetrability isn't thanks to composite, but rather sloping. The Strv 103C has an incredible frontal slope of over 75 degrees. This results in a lot of ricochets from outdated types of munition, which lack significant velocity to damage the tank. Chemical rounds, which penetrate high amounts independent of velocity, have a higher likelihood of penetrating the vehicle. These shells don't bounce off as easily, while still carrying large penetration values. In order to counter this, the Strv 103C was outfitted with a unique external armour package. Commonly referred to as a "HEAT fence", the Strv 103C is able to counter upper-plate detonations by fusing them ahead of the armour itself. This hinders chemical rounds from causing heavy post-penetration damages, which increases frontal impenetrability. The lower plate has also been strengthened by the introduction of a dozer blade. This adds an extra 20mm of angled armour, which comes handy against stronger types of munition. The sides have also been slightly enhanced by the introduction of 5mm fuel-canisters acting as side skirts.

Internal survivability

Once a shell penetrates the vehicle, the Strv 103C has to rely on its layout. Since the S-tank is entirely hull-designed, everything is incredibly compact to accommodate its varying features. The engine is placed at the front of the vehicle, followed by the crew compartment and lastly ammunition storage. When a frontal penetration occurs, a tanker can consider these compartments as varying grades of damage. Engine penetrations are usually fine, as the only way to take the tank out is by igniting it several times. Shells reaching the crew compartment can be severe, as the tank only has 3 members. Thanks to the last-stand feature, only one member needs to be alive. This can result in a lot of tanked hits, since it's difficult for the enemy to locate which member is still left. Finally, the Strv 103C is usually destroyed in a single hit if the post-penetration is strong enough to reach the rear ammunition storage. A tanker can still luck out if the shell penetrates the left-side when carrying 26 rounds, as only the right side will be filled.

A universal strength is the upper ribbed armour package. Previously introduced on the Strv 103A, this package allows the Strv 103C to “shred” incoming projectiles. Thanks to the introduction of volumetric shells, no sub-caliber round can currently sneak through this package. Due to heavy angling, and being placed behind the fence itself, it reaches thickness levels of between 500 and 1200mm, making it one of the strongest armour layouts in the game.

A universal weakness is slightly above and below the sharp edge where the upper and lower plate meets. This area can be easily penetrated by both chemical and conventional rounds. With varying damage depending on post-penetration effect. Aiming below the gun-barrel can also knock it out in the process, leaving the Strv 103C incredibly vulnerable.

Pros and cons

Pros:

  • High penetration shells - Access to Swedish DM23 rounds
  • High survivability - Able to tank most rounds from the front
  • New HEAT "fence" - Counters most Chemical rounds
  • Strong turbine engine - Gives the tank high mobility & good off-road performance
  • Low silhouette - Capable of hiding behind walls and small hills

Cons:

  • Weak to Sub-caliber shells - Compact design results in high post-penetration damage
  • Weak side & rear protection - Unable to survive against any high-caliber round
  • Unable to fire while moving
  • Difficult to aim - Relies on terrain below for stabilization, causes inaccuracy at longer ranges
  • Poor stock performance - Weak stock rounds and slow acceleration
