Are the tactical and support packages in specializations available offline as well?

all details welcome.

If you are solely offline with no updates from the original game, the operator and wetwork are available. If you downloaded recent updates, all are available, but if you connect to online later, you may lose you rank

Everything for 70 Levels is available. You need to connect to live to go past 70.
