Those were meant to be for the guys playing with a playable destroyer if you see who I mean, there is another mod for the IJN submarine torpedoes.
what do you mean added to one of the campaign layers ?
btw I'd like to make an IJN campaign next, waiting for the 3d import from skwasjer later on to fully mod the ijn subs. Like they did recon all australians harbors etc..
