Nulli, just because you are prior enlisted - does not mean you'll make a good officer, or that your men will respect you. I can promise you, you will have to earn every bit of respect your men give you.
I was enlisted until I reached E-7, then went over and started from the bottom of the O side. Would I say I received automatic respect from my men? No. I did, however, have a good rapport with them because I knew where they were coming from and they knew where I came from.
You'll have to earn their respect, as enlisted or officer - but being prior enlisted will help you relate better and they will feel a bit more at ease while taking you for a test drive.
I've seen bad officers from all walks - and trust me, your men will not give two shakes if you're prior enlisted if you are a piss poor officer.
