What other missions other than patrols?

[brumbarchris]

Hello,
I am playing the game just plain as it is without any mods (curious of what they are though I don't know how to install them)or patches. My question is: are all the mission going to be patrols? Or there will be some special missions (for instance some escorting or waship engagements during the invasion of Norway or something like that)

Regards,
Chris
