[U49]

My primary task is to interrupt the supply routes to the european theater.
Secondary task is to neutralize enemy battle assets.

That secondary task can be fulfilled either by inflicting damage to high profile target like carriers or battleships, or by threatening primary targets, so valuable destroyers are bound to defend my primary targets.

To fullfill these tasks I need to close in on my targets. That means passing the outer screen....
If I have a good position and good target solution (to a convoy) I go deep and silent to break UNDER the screen but TOWARDS my targets.
If my posrion is not favorable or I'm still missing data about my target I need to stay on at least PD. Even if this means to fight my way THROUGH the escort screen.
