Wolfpacks, radar and shadowing?

[sublynx]

Thanks Rconch! This helps a lot. I would also like to specify my problem a little bit more. The problem is not just attacking the convoy but also the need to follow it for many hours in order to send contact reports of it. I use H.Sie's V16 mod, which incorporates wolfpacks and in order to see a wolfpack one must first follow the convoy until night time and send regular contact reports.
