Pros and cons
- Powerful 40 mm HEF-I shells (Mk.II) with high amounts of explosive filler that can shred planes to pieces with successful 1 hit
- The M81A1 AP rounds can easily deal with sides of medium tanks and can damage cannon barrel and tracks
- Acceptable muzzle velocity for the gun
- Acceptable rate of fire
- The 40 mm shell penetrates up to 76 mm of armour, not enough to deal with some German SPAAs
- Muzzle velocity and rate of fire are not really good
- High leading angle is needed to hit the enemy aircraft
- Not suitable gun for higher tiers, especially against jets
