Comparison with analogues
- Bofors L/70 Mk.1 (57mm): An up scaled 57mm variant with more firepower found on the Begleitpanzer 57.
Usage in battles
The Akan m/70B is a multi purpose auto cannon. Using APFSDS means that you can eliminate a well protected MBT, even from the front if a weakspot is penetrated, although flanking maneuvers are better suited as the post penetration damage is poor with APFSDS. Lighter targets such as IFVs and SPAAs will stand no chance against this auto cannon with its fast fire rate and its APFSDS. The Akan m/70B is also equipped with HE-VT, able to deal with helicopters and against jets. Best to use HE-VT against aircraft proceeding on their attack run, and catching them off guard.
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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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.
