If your goal is to become a CRNA this is what you should do.
If you have your BSN, Direct Commission if you can. Remember your constructive credit (time which counts toward your rank that you come in as) will only count if you are an actual RN with your BSN. So if your an associate degree nurse worked 6 years none of it counts. You get half credit if are are a BSN RN, So if you worked 10 years as a RN BSN you will get 5 years and may come in as a O3 or maybe an O2.
Why would anyone ever want to go into the Enlisted side if you have your RN, BSN? It makes so much more sense financially and professionally if you are trying to truly become a CRNA.
Remember the Army has the #1 Nurse Anesthesia school in the country. The army will send you for free (well you pay them back about 5 years).
Remember the Army has a 20k per year bonus for 4 year commitment with a MED Surg, CCRN, or OR certification.
So I guess I would reccomend this if you are attempting to truly no ******** going the crna route and want to be in the millitary.
go to the icu/er course after you get in
take your GRE/shadow crna
apply for lthet for crna school.
As for this "leadership" stuff your talking about, I am not really tracking. You said it is for your "future" job. If you want to be a crna than this is the route you need to take and don't ******** around with a public health/prev medicine job.
