No, no, no, no diving...
That first picture is precisely the moment you yell Feuer Frei *and have your flakvierling take that thing to the cleaners, then at the very last moment you make a hard turn so the burning wreck doesn't sink your boat.....
If for some inexplicable reason you do no in fact have a flakvierling...well, you should have been well on your way to 30 meters by the time it's that close....
* if you were shooting at it before it's that close this is precisely the moment when your brave men are reloading the aforementioned Flakvierling and they will start firing again just when the bombs hit....
