Tank cannons
The 120 mm Kan Strv 121 is the Swedish domestic production of the famous 120 mm Rheinmetall L/44 cannon.
The Kan Strv 121 offers a balance of firepower, accuracy, and sustained rate of fire. This L/44 variant is reasonably accurate at long range with any ammunition, however minor round deviation may be evident at extreme ranges (over 2,000 m).
It has three rounds available to it: slsgr m/95, DM13 APFSDS and DM23 APFSDS. Of these, only DM13 is available when the vehicle is stock, with slsgr m/95 as a tier 2 and DM23 as a tier 4 modification. It's advisable to primarily rely on the best available APFSDS round for engaging other MBTs. HE should rarely be used but can prove to be useful for more experienced players.

Cons:
Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.
Excellent additions to the article would be video guides, screenshots from the game, and photos.
