All right, thanks.
Do you know what elements contribute to increase this combat bonus ? Is it the ship commander or the Fleet commander (or both) ? Is it related to some actions the ships accomplished or is it more or less randomized ?
Also, if it's a combat bonus, I guess it is unrelevant and useless for any civilian/commercial ship for those guys usually do not bother to keep the green tentacled blobs from Andromeda away from our beloved homeworld (shame on them) ?
