US Immigration from Belarus

Does anyone know how to find out your case number in a queue at embassy? Do we need to call to the embassy or write?

I've tried the military help email through USCIS and their military number but so far havn't been able to get past automated systems on this. I figured it wouldn't hurt to see if I can get a quick answer here.

I've been in the military for 10+ years with the changes in locations that come with it. When listing my employment history would I be able to list just the military and the address provided on our W2's for the entire duration I've been employed by them or does the process require that I list each base individually as separate employers for the purpose of the petition?

Thanks for the help.
