Master sergeant

From Memory Alpha, the free Star Trek reference.

Master sergeant was a military rank, a traditional infantry or army enlisted grade held by a non-commissioned officer. In comparison to naval ranking systems, this rank was approximately equivalent to the naval chief petty officer or senior chief petty officer grades.

This rank was used by the United States armed forces, where it was senior to staff sergeant and junior to first sergeants and sergeants major. On an planetary duplicate of Earth, a boy named Jahn wore a master sergeant patch, among others, on his jacket. The insignia was styled like a US Army master sergeant, three chevrons above and three rockers below, with no center insignia, but the patch seemed to be sewn in US Marine colors (where the Marine master sergeant patch would have crossed rifles in the center field).
