What I mean by saying I have seen them in the Mediterranean, I don't mean it's accurate, I have just seen them there, I believe to have even seen two Auxiliary Cruiser Komets guarding the same convoy
, I have even seen two Emden Class Cruisers at the same Port, (There was only one of this ship) one was at dock, the other was escorting the convoy. Ill do some more "Convoy watching" to see if i can get a screenshot of this.
So im just saying what i see in game, this has no regard for historical accuracies.
And if we look back at the stock game, there was only one HMS 'Rawalpindi'. If you take a look at Scapa flow or Loch Ewe you can see about two-three of them parked next to each other, and in two of the stock missions you have to "Sink five AMC ships" and Rawalpindi Armed Merchant cruisers are the only ships that qualify.
This game has quite some inadequacies.
