Boni as in the plural Bonus.
I wasn't asking about how staff officers' bonuses affect ships in their task force, but if the bonuses/boni used by the staff officer positions can also be used by ordinary ship commanders.
For instance, if Commander X with a Logistics bonus of 10% is assigned to Ship Y, does his Logistics bonus do anything beneficial (since he isn't the logistics staff officer)?
Sorry for being unclear.
Logistics speed up the loading and unloading of ships.This only affects cargo holds, cryogenic transports and troop transport bays. So it's useful to appoint commanders with Logistics to such ships, though I mostly use it with troop transports only, as it's unlikely that all cargo ships in a TG will have identical bonus, meaning that some ships would have to wait for others to load - or I might not have enough Logistics commanders in the first place.
The bonus is not relevant to any other ships.
