Commemorative Coin

[Huginn]

rotc, mcpo, cmc, ntc.... Why do military people abbreviate everything like this? The rest of us have no idea what you're saying T_T

Please forgive me. Reserve Officer Training Corps, Master Chief Petty Officer, Command Master Chief, Naval Training Center, HospitalMan Chief Master.

and a Command Master Chief is the head Non-Commissioned Officer of a particular ship or station.
the CMC, having trained you to be an officer, would be at your commissioning and would often be the first person to salute you, as you would now outrank him.
