About Seeker swarms,
Well, if I can't actually experience the supposed abilities of the Seekers, I can't really implement them. Of course, the Seekers could crawl into the gaps of armour.
The Warp is also interfering with the communication on Mars, and before that, there was a dust storm. I never knew about the open-air designs.
I always thought she was bit on the neck? But yeah, there is no mark on the neck, so it does seem that the bug bit through the pink fabric. Well, in the thread's context, bugs biting the armour of something, which is several inches away from the body (I imagine there's quite a bit of space between the Ultramarine's armour and the actual body), that the Seekers' bites won't pose an immediate threat to the Chaos Space Marines. Unless a hole is busted open in the armour, or the Seekers crawl into a gap.
About jamming,
I suppose the Collectors will start jamming, but the Chaos Space Marines are not. The Warp is doing its own jamming for now, but Rem is reestablishing connection with the fleet, regardless of the Warp or Collectors. Short-range communication will still work; I sure won't care about specifics of jamming unless it is mentioned.
