General info
Tell us about the tactical and technical characteristics of the cannon or machine gun.
Available ammunition
- BR-240: APHEBC - This should be the main ammo type that you use, as it deals the most damage because of its explosive filler.
- BR-240P: APCR - This shell should only be used against more heavily armoured targets that the BR-240 cannot penetrate.
- BR-240SP: APBC - It is recommended to avoid this kind of shell as it is inferior in most aspects compared to the BR-240P ammo.
- O-243: HE - Carry only very few of these. They are useless against anything other than unarmoured AA vehicles.

Comparison with analogues
Give a comparative description of cannons/machine guns that have firepower equal to this weapon.
Usage in battles
The 45 mm 20-K is a decent gun for its rank. In downtiers, it is a very effective and lethal weapon, and can take out most tanks with 1-2 shots. However, in uptiers, it will be more difficult to take out tanks because of the relatively small calibre. However, this doesn't mean that you are useless. The APCR round is capable of penetrating most rank II vehicles, however the post-penetration damage is poor due to the lack of an explosive filler.
Pros and cons
Pros:
- Decent penetration
- Short reload time
- Has access to APCR with 104 mm of penetration at point-blank
- Shells have a medium-high velocity, makes aiming easier
- APHEBC are some of the best at rank 1
Cons:
- Due to the small calibre, post-penetration effects are bad
- APHEBC rounds will have trouble against heavier foes
