Editing Medical Officer (section)

==Specific duties==

CMOs aboard a starship or starbase are directly in charge of the sickbay or infirmary, commanding medical department personnel and activities. The CMOs' primary duties are the oversight and maintenance of the overall health and physical fitness of crew and passengers.

Officers likely to be assigned as the CMO over long-duration missions of exploration, have scientific training in disciplines outside of medicine, allowing them to take on major, extended research projects; or to better participate in a wider variety of encounters.
