Fired my 2 stern homing torpedoes. It listens to the engines of ships.
I followed my 2 torps on the attack map and i saw them makinq a circle ( target was in front of me) and i was like OMG !! I raised my observation scope and looked behind me and those torps were comming for me !! Quickly managed to turn of my engines and they barrely missed me. It sank a ship though
