The Strf 9040C is a modernized version of the Strf 9040, developed by BAE Systems Hägglunds in Sweden. Compared to the A and B versions, the Strf 9040C comes with a new turret with improved protection, enhancing the survivability and situational awareness of the crew. It was also equipped with air conditioning that made it more comfortable for the crew to be deployed in warmer climates and for more international usage.

The Strf 9040C was introduced along with the initial Swedish ground tree in Update 1.97 "Viking Fury". Having high mobility in all terrains and a fast-firing autocannon, it is an excellent nimble and hard-hitting light tank for the Swedish line-up. Compared to most IFVs found in the game, the Strf 9040C is quite different to its peers. The tank has no anti-tank missiles, and sits at the highest ranks, facing vehicles other IFVs never get to experience. This is due to the design of the vehicle, as the Strf 9040C features a reliable 40 mm Bofors cannon which should be familiar to most players. However, this cannon fires APFSDS, capable of shredding any opponent from the side, even frontally in some cases. This compensates for the lack of missiles, and results in a highly versatile vehicle capable of disposing of several opponents at once, as it can fire up to 24 shells in the span of 12 seconds.

If the anti-tank capabilities weren't enough, the cannon features proximity-fused HE shells, capable of tearing apart any unsuspecting aerial opponent. This feature is incredibly useful in higher tiers, as close-range helicopters and attacking planes are incredibly common. Despite the Strf 9040C lacking any form of radar equipment compared to its SPAA counterpart, the Lvkv 9040C, the tank can still effectively deal with aerial targets, especially at closer ranges.
