-[[Strv m/41 S-I]] got a similar playstyle as the original [[Pz.38(t) F]] though it is equipped with a swedish Bofors 37mm kan m/38 which is the same cannon on the other swedish light tanks and the Lago I. The cannons regular APBC and APHE shells penetration capablities are a bit on the weaker side, it still got a saving grace and it is the capability to use APDS rounds.

The cannon's regular APBC and APHE shells are a bit on the weaker side in terms of penetration, but it has a saving grace in its ability to use APDS rounds.
-Even though Strv m/41 S-I is a light tank it got armour compareable to that of medium tanks like the [[Panzer III Ausf. J]] or the [[Ho-I]], Frontal armour is as thick as 50mm on both hull and turret. Though it got a hard front, the sides and rears are less than desireable when it comes to armoured protection making the sides and rear vurneable to heavy machine gun fire, auto-cannon and larger cannons which will easily incapacitate the Strv m/41 S-1. Hence the Strv m/41 S-1 should be aware of its surroundings and not expose the sides or rear too much for the enemy.

-Similar to the [[Strv m/41 S-II]] its mobility is decent, but not the greatest to get into a good frontline position like the [[M5A1]] or [[BT-7 (Family)|BT-7]] due to the lack of speed and accelaration. Making it vurneable on the move to a position where it can play to its strengths, but when a [[Strv m/41 S-I]] is in position it can be a thorn in the enemies sides with its APDS rounds.

-Strv m/41 S-1 like most early Swedish light tanks excel in an entrenched position or in an ambush position from a distance where the it can depend on its APDS rounds to penetrate enemy targets at long distances, though its APDS is lacking in the post-damage it can still out range most vehicles with a decent accuracy being able to even knock out vehicles like [[M10 Wolverine (Family)|M10 Wolverine]] at distances with well placed shells. Strv m/41 also got an excellent gun depression, making it very efficent at peeking over hills without exposing too much of the vehicle itself. Also peeking over hills will increase the armor protection due to the 50mm armour being at an angle, this will make it a very efficent vehicle at higher positions.
