When Windows Defender was saying the same thing about past versions I still had I knew something was wrong. This started right after the latest Windows update I got. I had to exclude the folder I stick the installer in.
I just checked that one, there isn't any instructions like the others. Perhaps Aslain or MajorRenegade can answer your question.
Usually you see something like this in the mod installer:
On the mod you selected, there should be some notes (at the bottom I think?) that tells you what in game crosshair you have to select to get the modded crosshair to show.
I'd prefer if they changed the ranges to yards, that way you'd know exactly how many nautical miles to your targets (2000 yds = 1 nm), speed is fine the way it is IMO.
That's something I've not seen anywhere before. Working like shell tracers should be legal, it won't show the torps before they're spotted so no advantage. Be interesting to see if someone can make something like that.
I may have misunderstood things, I thought he was talking about a bubble or indicator on the map. That wouldn't be allowed but something on the panel to indicate range would be ok. My bad.
