Okay, so who beat me to it?

[ReM]

I have encountered convoys with a circle as their symbol on a couple of occasions as well and I'm pretty sure there was no submarine in the convoy....

There were U-boats present though.....I'll post some screenies if I can recreate it!

The radio reports ( which give you the map update and symbol ) come from the lead unit
If its a sub its round
A merchant and shows as a convoy
A warship and shows as a TF

The Sub wont necessarily be in the middle of the convoy as its classed as a warship so will usually be in one of the outer rows

AI subs tend to run a little slower than the speed they are given so by the time you get to the convoy the sub will have dropped back slightly

Or be dead lol

Thanks for you explanation..I"ll have a look for Mr sub if I encounter another one of those...

I have tried to sink one in a convoy once....it took a hit amidships and didn't even budge.... hardly worth the eels...
