I don't think we have specific relations with any Junker-based player faction. Our rep-sheet is however hostile, but bear in mind that HF cannot freely attack transports. Under typical scenarios Junkers would likely be ignored or, at most, questioned as to their cargo or intentions. ....
Maybe from a HF point of view; the less enemies the better.
Even though we are friendly towards Rogues and hostile towards Xenos, the last post clearly meets our point of view too.
Looking forward to a carefull neutrality then ;-)
