Comparison with analogues

• The 20 mm Oerlikon KAD has a higher fire rate but slightly less penetration.
• The 20 mm M168 has a far superior fire rate but slightly less penetration.

Usage in battles

Because of the fast rate of fire and the HEFI-T* shells found in most ammo belts, it is an excellent anti-air weapon, even against jets. It is also capable of disabling tracks in a very short amount of time.

Pros and cons

Pros:

• Fast-firing autocannon
• Able to fire APDS (for a few vehicles)
• Majority of ammo belts include HEFI-T* allowing anti-air capabilities
• Great at disabling tracks

Cons:

• Low penetration even for APDS
• Overheats easily
