Welcome to the boat mate.
You don't get flamed till your post count reaches 10
I do as Randomizer does. Feel like you should do the mission if possible.
Intel gathering, that sort of thing. Can't lock on the port facilities so just have to do the ships. Pro tip take your pictures first and than sink all the ships. If you can take out the DD than you have free run.
If you don't complete the mission, no big deal, sink enough ships and all will be forgiven.
Good gaming choice Sh5 will be a good sim in 6 months or so. I won't get it till OSP is removed.
Good luck and good hunting.
