In real life, the Germans found the 3.7 cm shells of the 3.7 cm FlaK 43 on the Ostwind to be more effective than the 2 cm shells of the 2 cm Flakvierling 38 L/112.5 on the Wirbelwind.
ack-ack
Well yes, each individual 37mm shell would do more damage each individual 20mm shell, but what I'm asking is,
Is the total damage done by the 4 20mm's on the wirb equivelant to, less than, or more than the damage done by the 37mm cannon on the osti, assuming all shells hit?
