My main problem is its penetration. In one game, It almost killed 3 of my Pumas.
Puma is an armored CAR.
Bofors is a 40mm AA gun.
If axis 40mm AA flak penetrates TANKs, what makes you believe allied 40mm flak shouldn't penetrate CAR?
anything lighter then ostwind is and should be ripped apart by it when it comes to armor.
