The direct torpedo
- small boat
-requires one to sink small boats, However it is a lot easier to sink a boat with surface torpedoes - rhib
-requires two to sink a rhib, However it is a lot easier to sink a boat with surface torpedoes - submarines
-requires two to sink both types of submarines
Hard to aim in both subs due to the lack of crosshair and aiming mechanism, However if trying to shoot another submarine it can be easier to aim in the duo submarine because you can line up the dot on the radar with the top line of the radar scanner so you know when you are lined up for a direct shot
