Correction.
Kronan has NEVER made Varyag passengers KOS. We did make all Varyag crew KOS but only after Yoshii declared war on us. Which by anyone's standards is only right and reasonable.
Despite her claims to you, or others we have rarely even bothered to shoot back when shot at by Varyag in TG or our mobs cleared by them. When we are on a skill run for repairers then that is our main aim, so whether it be mobs or bullets hitting us it is all the same, Damage=repair skills.
As for the passenger (note singular) on the night we attacked Varyag at Arkadia, I made a point of checking with them after and they were not shot.
So why did we do this, well from my point of view however petty, it was a case of dishing a dose of her own medicine. After all Varyag has attacked us during our scheduled warps, multiple times, even before the NVE involvement.
links of the videos have been posted here on forum on several occasions
and 1 further point... NVE/Varyag involvement extended beyond Kronan and Normandie, as they also shot down at least one Pathfinder to my certain knowledge.
