Heavy Cannon

[Baron von Beergut]

I've been kind of busy lately, so not keeping up on things here.

Could someone explain to me how the Heavy Cannon works for the few planes that have it? Or direct me where it explains it?

I understand the burst and bonus but not the advantage of Heavy Cannon.

Thanks in advance for any responses... BvB
