Description

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.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

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
