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.

(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

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against the main 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

Summarize and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.




Examine the history of the creation and combat usage of this weapon. If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ History" (example: and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article.


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