General info

The Flak38 (20 mm) is a very impressive autocannon, having an extremely good fire rate, and a good selection of belt types. It can be used to fight both air and ground target. The HEFI-T rounds will take planes down with a few shots, while HVAP-T has high penetrating power, enough to deal with most tanks at its BR. Although the HVAP-T rounds' post-penetration damage is poor, it makes up for that with its amazing fire rate.

Available ammunition

• Default: API-T · HEFI-T · HEFI-T · HEFI-T - Half of the shells (HEFI-T) are useless against tanks while the other 50% (API-T) is useless against planes. However, this belt is reliable against open-topped or lightly armoured vehicles like SPAA.
• Sprgr.: HEFI-T - This belt is only useful for fighting planes or lightly armoured/open topped vehicles.
• PzGr: API-T - This belt offers a good transition from the Default to the PzGr 40 APCR belt. The round offers decent use and damage against lightly armoured 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 · API-T - This belt is best for fighting tanks. While the damage effects post-penetration are quite poor, the rapid-fire from the autocannon will wreck most tanks at this BR. In close combat, these shells should be used against modules and crew members to make the most of each shell. Against angled armour however, the APCR ammo may not be very effective.

Sprgr.	2	2	2	2	2	2
PzGr	36	34	26	19	14	10

Usage in battles

The FlaK38 (20 mm) is a very versatile cannon. With its high fire rate and access to HEFI-T rounds, taking planes down will be an easy task. It can also be utilized to fight ground vehicles, as the HVAP-T can penetrate 64 mm of armour at point-blank range. Although the post-penetration damage is poor, the high fire rate makes up for this fault.

Pros and cons

Pros:

• Very high fire rate, will take down planes very quickly
• Can fight ground vehicles
• 64 mm of penetration with the HVAP-T round

Cons:

• Reloading rate is slow compared to other AA guns at its rank
• Magazine is emptied very fast when firing continuously

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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

An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.
