Hi ingsoc84!
The flag is from TDW's Sub Flag Mod, you can find it here:

My mod will work with the english speech, but ofcourse it's going to be bit messy. I'd suggest you switch to german speech, I don't personally know german language but it really doesn't matter that much, and the immersion is waaay better than with the english speech. And you learn a bit. You don't need to re-install, there is a mod that switches the audio. I think it is here:

And after that, you must also apply KarlKoch's speech fix mod, it adds many audio things that were missing in the game, it has even english version. Here:

PS.
...more shouting, more tension, more things that go boom! I think I put that a bit wrong, this is no Hollywood action mod! I try to make it realistic and close to the world of Das Boot. Submarine shouldn't be like some ultra clean spaceship, but a metal tank full of sweat, anger and fear!
