Comparison with analogues

40mm Bofors L/60: An auto cannon where the Bofors 40mm L/70 is derived from.
M266 (40mm): An American variant of the Bofors L/70 used on the M247 "Sergeant York"
Bofors L/70 Mk.1 (57mm): An up scaled 57mm variant with more firepower found on the Begleitpanzer 57.

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Pros and cons

Pros:

Has access to APFSDS which can knock out any opponents it faces.
Has access to HE-VT which can deal with any helicopters and aircraft.
High fire rate.
Good penetration for an autocannon.
High ammo count.

Cons:
Easy to go through the 24 stage ready rack.
Post penetration damage with APFSDS is poor.
Slpprj m/01 can be expensive to field.

History

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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 />.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.

External links

Paste links to sources and external resources, such as:

topic on the official game forum;
