Hey lord BTW the 8/8 and 8/6 means it rolls a secondary attack. German Jet fighters have this because they were able to use their speed to attack a fighter two times in the time it would take that prop plane to get a good look at a Me-262. They were able to even ignore fighters and strike at bombers and then get a pass at the fighters again.
Battleships get a secondary attack that is not preemtive. The first (highter number) is a preemtive attack.
The carriers take 2 hits
german Type XX1 is preemtive even against destroyers and cruisers
Katyuskas are preemtive
self propelled artillery hits go against tanks first
armor hits go against artillery or armor
infantry must go on infantry first
Artillery attack preemtively in the first round only
Tanks +1 attack with matching plane 1/1
Infantry +1 attack with matching artillery 1/1
Artillery +1 movement with matching armor 1/1
many other rules make the numbers look more understandable. Many ask why does a battleship etc. attack twice… but if you look at the other rules as a whole the values are perfect.
