Do Navy Nurse Reserve OFFICERS have to complete boot camp?

EVERYONE going into the military attends SOME type of basic military training. Not sure how long the Navy's officer training is though.

Navy officers complete a course called ODS. It's a few weeks long and it isn't basic. However, it is the military, and they expect you to pass the physical fitness test before you leave. ODS (as best I can tell) is a compilation of courses and classes that Navy officers complete before they go to their first duty station. It is attended only by direct commissionees, not ROTC grads.

For current or former Officers of military branches other than the Navy (OSVET), as well as for Officer candidates without prior military experience: You will need to meet the initial leadership training requirement by attending the twelve-day Direct Commission Officer School (DCO) in Newport, RI. This will count as your first Annual Training.
The Navy Reserve offers flexible training options that fit the busy schedules of nursing professionals. That means you can comfortably balance your civilian and Navy schedules while enriching your personal career experience.
If your specialty area lies in anesthesia, operating rooms, medical/surgical or critical care nursing, your skills are highly valued in the Navy Reserve, and your service will be rewarded accordingly.

Every member of the Armed Forced is required to complete a 6 week-minimum basic training course!

This is not true. Requirements vary by branch and by active vs. reserve. The active Marine Officers complete the 9 week basic training with enlistees. Active Army Officers (such as myself) complete a 12-week med-specific course in San Antonio, TX. Active Navy Officers who are not ROTC grads complete ODS, which is 3-4 weeks long from what my coworkers tell me.

Reservists are always the exception to the rule. Army Reservists were only with us in training in San An for 3 weeks.

Due to recent changes in the military overall, I would strongly suggest you speak to recruiters. Not enlistee recruiters, but nurse recruiters specificallly. They can tell you what the requirements are and what your options are much better than any of us can.

SoldierNurse22 is correct. In Army ROTC we had a one month field leadership course our summer of third year to our fourth year. We did not have the enlisted basic training (unless you were already a prior service member). Talk to a nurse recruiter and they will give you the correct information.

Marine Corps Officers do not attend "basic" with Enlisted Marines. USMC Officers attend Officer Candidate School (OCS) in Quantico, VA. It can vary in length, depending on the program through which you enter the Marine Corps. ROTC candidates go for 6 weeks. PLC or OCC candidates go for either 10 weeks or they go for 2- 6 week periods, in separate years (e.g.- after freshman year and again after junior year). The only USMC Officers that do not go to OCS are Naval Academy graduates. All Marine Corps Officers attend TBS (The Basic School), for 6 months, after getting commissioned and then head out to their MOS school. Marine Corps Boot Camp is 12 weeks and takes place in either San Diego or Parris Island, SC. The men are split between the two, and all women go to PI.

The Marine Corps doesn't have medical personnel anyway, so it's pretty much a moot point, but I just wanted to correct something that was said earlier by someone else. Sorry about that.
