I read the Battlefleet Koronus, but I didnt understand the damage system in the Rules of War. There is no example.

How big is the unit's damage? the damage of their weapons? So infantry with autogon 1d10+3 and infanitry with hellgun 1d10+4?

Thanks.

PG 123-124 Under unit Characteristics

First you figure out a unit's "Power" stat which is based off it's: Base Power + light, medium, or heavy mod + Tech Level

It then does 4D10 + Total Power characteristic.

It's armor is Total Power x2

Thank you, I missed this section.
