This second edition to the Chief Petty Officers Guide updates and modernizes the first, and has been written to serve as the companion guide to Chief Petty Officer (CPO) development processes and tools such as CPO 365, CPO mess training, the Senior Enlisted Academy, and books and articles written for and about the CPO mess. Its target audience includes serving CPOs/SCPOs/MCPOs, first-class petty officers, officers, civilian managers, foreign naval officers and senior enlisted, U.S. Coast Guard CPOs, and sister-service senior enlisted. This handbook provides unique insights into the values, beliefs, attitudes, and skills which enable CPO success, how Chiefs use power bases, influence tactics, and managerial skills to achieve objectives, and how Chiefs influence their peers and support and develop the wardroom.
