I just wish to mention here (for anyone that may be doubting my level of 'seriousness' towards the game) that I play with 85% realism having only map contacts and stabilize view 'on' ,I play the game like a true sim operating in the area BDU sent me and taking full precautions in all my actions,however after a few days in the assigned area and if there is no action then I usually assign myself new patrol zones,in no way do I play this game like a 'shooting gallery' ,no,what happened to me would have happened to anyone with any amount of aggression and initiative in them,you fortuitously encounter a large convoy containing a major battleship in a most random manner 'out of the blue',and you take your chances and attack them like a wolf,never letting them go!.
As I mentioned earlier,this was the only time I ever encountered a major warship and successfully destroyed it,and its instilled in me a great bloodlust now,just like the Viking berserkers i've read so much about hehehe
I KNOW some of you will understand me here,if not,you'll know it when it happens,and its great!
