KwK30 (20 mm)

Description

The KwK30 (20 mm) was primarily as the main armament of the Pz.II C and the Pz.II C (DAK). The KwK 30 also served as the basis for the 20 mm C/30L, which was used on the He 112 A-0. An improved version that had a higher rate of fire, the 20 mm KwK 38, was mounted on the Pz.II F.

Belt types

Belts	Shell composition	Combat usage
Default	API-T, HEFI-T (Armour Piercing Incendiary tracer – High Explosive Fragmentation Incendiary tracer) shell	The belt composition means that 50% of the shells (HEFI-T) are useless against tanks while the other 50% (API-T) is nearly useless against planes. However, this belt is reliable against open-topped or thin-skinned vehicles like SPAA vehicles. Since there are no dedicated high-explosive shells for the selection, having one belt of this in reserve does not hurt for those situations.
PzGr	API-T (Armour Piercing Incendiary tracer) shell	This belt offers a good transition from the Default to the PzGr 40 APCR belt. The round offers decent use and damage against lightly armored tanks, especially at close range. Due to lack of high-explosive filler however, it is better to focus on the PzGr 40 belt to maximize penetration power.
PzGr 40	HVAP-T (High Velocity Armour Piercing tracer) shell	Probably the best belt with the best penetrating shell for the vehicle. While the damage effects post-penetration can be quite poor, the rapid fire from the autocannon can mitigate this problem by following up quickly with another penetrating shot. In close combat, these shells should be used against modules and crew member to make the most of each shell. Against angled armor, however, the APCR ammo may not be very effective, just like any other APCR shell.

Comparison with analogues

Give a comparative description of cannons/machine guns, that have firepower equal to these type of weapons.

Usage in battles

The high fire rate and excellent penetration of the Kwk30 (20mm) allows enemy tanks to be killed quickly. However, a small magazine and a lengthy reload rate allows enemies to fire back and destroy you. After shooting at enemies, take cover to reload. Try to avoid long-range engagements, as the penetration rate drops off rapidly at around 500m.

Pros and cons

Pros:

• High fire rate, does a lot of damage
• Very good penetration at close to medium ranges
• Decent reload speed of 6~7 seconds
• Better penetration than other 20mm cannons at its rank

Cons:

• Poor penetration when not using HVAP-T shells
• Penetration rate drops rapidly at longer ranges
• Relatively small magazine of 10 rounds
