You are correct. Officers just get dismissed. However their characterization of service on their DD-214 will still reflect one of the five characterizations below:
There are five (technically six) characterizations of service, two punitive (awarded at a courts martial) and three non-punitive (non-courts martial discharges). The two punitive ones are:
Dishonorable
Bad Conduct
The three non-punitive ones are:
Other than Honorable
General
Honorable.
There’s also entry level which i don’t believe gets a characterization.
