You need to make CPT and then go do your company command first. NCOs train NCOs and enlisted soldiers. Officers only train officers of lower rank. Ergo your population is going to be 2LTs and you will have to answer questions on rating LTs...and I'm guessing you haven't rated any officers yet.
Go find a CPT job to get promoted and then do your staff time until you can find a company command. Then after command and you are branch qualified you can look at being an instructor.
LT, I was in the NG and switched over to the reserve side and found that the promotion system is a lot easier and better to navigate. If you are looking to work on the Drill Sergeant side, I would recommend the reserves. They have a regiment that is dedicated to drill slots. I was able to command a company and it was one of my best units.
If you are looking to get promoted, in the reserves we don't wait for slots to open up, we actively seek slots that will allow us to get promoted and enhance our careers. You are your best career manager and you will have to do what is best for your career as an Army officer.
