Army OB/GYN RN

Hi everyone! I'm getting ready to submit my packet for 66G (OB/GYN). I've been looking for other Army RN's in the OB field, but have not been able to find any info in either thread. A little background: I've been in OB for 18mo, will be submitting my packet in Oct. I am prior service: 5 yrs AD enlisted (medic). I'm looking for Army L&D RNs so that I can pick your brains about the process, your units, and experiences there vs civilian. I know that I will be going in, but I like to know as much as I possibly can before I relocate/change career paths. Questions: Whats the pt ratio? I do 2:1 right now. Do you work 3 12's, 4 10's, or "needs of the unit"? Do you pull >40 hrs/wk? Are you pretty autonomous? Do you handle the acute pts or send them to a diff facility? (I'm in a high acuity setting) Do you do LDRPs? Well thats all I have for right now. Even if you're not an L&D RN, maybe you might know someone who is?? Thanks everyone!
