Check the radar- these Centauri Raiders are friendly. I don't know the mechanics of how patrols spawn but my guess is that they might inherit the allegiance of the station that causes them to spawn or gate in. There was a Centauri-hostage commonwealth station (the ones that look like armor dealers) in this system. If my guess is correct, then it caused these raiders to spawn and they inherited its friendly allegiance.
I also like how hostile patrols will hunt down and attack non-allied, non-player ships, but if they chase their target all the way to the gate and their target successfully escapes, they sometimes start attacking the gate rather than choosing a new target.
I love the new, stronger ship variants that appear after St. Katherine's. The Mark V / Akan-equipped Manticore variant is especially cool! I am a little curious as to what kind of ship the suddenly-ubiquitous IAVs are supposed to represent- are they gunships? freighters? passenger vessels? some sort of utility craft? I've noticed that IAVs and freighters tend to snag all the good loot off wrecks and destroy them before I can get to them. This is frustrating but logical and it does discourage the accumulation of huge wreck piles.
