Here are the documents you need in order to apply for Chief Medical Officer (CMO) and Officer-in-Charge (OIC) positions:
With superior performance in these positions, CMOs and OICs make O6. It is that simple. Plus, by applying for these positions you get to compete Navy-wide, not just at your command like many director-level positions like DMS, DSS, MEC Chair, etc.
In other words, if you are a senior O4, O5, or O6 who wants to assume leadership positions in Navy Medicine, this is your chance. Apply.
