What is barrier ?
 

Hello from France and, please, excuse my bad English ! I am beginner with " quick mission " and I don't understand what is to " search a barrier " ( first mission ) Thanks very much

It means your patrol area is from point to point. you shouldn't allow to pass enemy between these 2 points.

Btw quick mission is really bad in DW

Submarines starts too close to each other

Only one good quick mission is for FFG "screen escort" on medium difficulity. And only if WASP speed is not too high (less than 20 kts)

welcome aboard!

OK
OK, I'm moving a lot! The coordinates are given by the mouse on the map, no grid like in silent hunter ?

The grid system in SH3/5 are the Germans Marinequadrant system to confuse the allies. They refrained from using or transmitting/receiving Lat Lon numbers in fear of interception.

Yes, unfortunately there is no easy way to draw the coordinates.
