I really think the officer we had was really good with my parent's application because he was surprised that my mum's interview date was weeks later after my dads and when I told him about that he looked into the computer and told me he will take care of it. A few weeks later my mum's application was approved with no interview, then a few days later the green card came in the mail. MAVNIs out there, please wear your dress blues to the interview for your spouse or parents green card interview. You are authorized to do so and it will only benefit your family's case. It really up to the officer's discretion to provide any additional assistance with things like that, but most of them are really good with the military background, hell, a lot of them were in the military.
