I found an interesting tidbit lately saying that the Icelanders don't exactly have much field experience on land - their military consists of seafaring hunters. In that case, losing contact in the field probably means that ship got sunk by a whale, not much point going to pick up surivors especially since that's the North Atlantic we're talking about, probably not much point considering water temperatures.

And the Danes - don't have much of a military left to speak of after their continued defeats, so it strikes me as unlikely that Sigrun even knows about whatever shape their protocol takes, unless Mikkel divulged some information. It'd be interesting to see her and Mikkel clash over this, if she were less sick - perhaps Taru and Trond instead, over Finnish vs. Norwegian tactics? And Taru says early on that she worked with Swedes in the cleansing of the Pori area, so she ought to be familiar with their way of conducting operations.

Aaaah, I want soooo much backstory fic for Sigrun out of this, though. It could slot quite nicely with the ambush that she mentioned, losing contact and hanging on until help comes. While at least two people die.

Bonus visual parallels, look at her posture and expression!
