What can I do with my ERB, since it is showing a 2 on the Command Sponsorship portion but I am on unaccompanied orders?

Let me change that last answer.

Youre on a command sponsored tour to Korea. That didn't just happen by accident. You had to have done an overseas EFMP screening, and applied for command sponsorship in order to have been approved. Korea is not like long tour areas where you could have accidentally selected the accompanied tour because it's the default. You had to do work to request command sponsorship to Korea and then be approved for it.

You got two choices, bring your family over or go change your tour type. If you don't, you won't be authorized to receive BAH for them at their location for much longer.

What your ERB says isn't really all that relevant a lot of times. If you're unaccompanied then your tour should be two years for a long tour area and one year for a short tour area. You can check that out by looking at your DEROS. If your DEROS shows the correct tour length then you're good. If not, then go to your S1 to fix your DEROS and change your tour type

I would start by talking to personnel...
