Yes a sub trap is a Q-ship, but Q-ship is a term originally used by the british in the 1st World War. For the japanese they were simply traps to lure submarines out and surprise them with hidden guns and a ship filled with empty barrels and wood (Making it difficult to be sunk). If you suspect that a ship you encounter is a trap, move away...they can be recognized sometimes by their zigzagging course and aggresive movements pattern (They use the AI ROES of a cruiser
)
Keep the reports coming, I like them
