General info

The 50 mm KwK L/42 is a decent gun for its rank. It has a quick reload rate of ~4 seconds, a decent APC shell and an excellent APCR shell with up to 132 mm of penetration.

Available ammunition

• PzGr 39 - APC - This is the main ammo type, use it whenever it has enough penetration to penetrate the target. It deals the most damage, because of its explosive filler.
• PzGr 40 - APCR - This variation of APCR is even lighter, slightly faster and offers the best penetration. Use these against the occasional T-34 and Sherman tanks, which have highly sloped armour and are generally very resistant to the basic APC ammo. However, don't expect it to cause any real damage upon penetration, as it has no explosive filler. It only deals damage to modules/crew straight in its path, so it is important to aim for vital modules.

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

This gun is best against low BR tanks with little armour like the BT-7, T-26, etc. At higher BRs, it is best to flank enemy tanks and attack their weak spots, since the gun won't be able to always penetrate every frontal armour.

Pros and cons

Pros:

• Quick reload speed of around 4-5 seconds
• Decently accurate and powerful
• Very high shell velocity for APCR rounds

Cons:

• APC shell with explosive filler struggles to penetrate common foes at its BR, such as the T-34 and M4 Shermans

History
