Captain T. Ginwald was a Human military officer who served in the United Earth Military in the 22nd century.

Ginwald was mentioned in Balthazar Edison's personnel file as his senior officer when Edison was a major assigned to force command. (Star Trek Beyond)

This character was only mentioned in writing.
As Edison served in the Military Assault Command Operations, it might be presumed Ginwald was a MACO officer. However, this was not stated in the file.
