For the Son'a rank, please see Subahdar.
In Angosian military ranks, a subhadar was ranked below an primehadar and above a third hadar.
Roga Danar of Angosia III, who served in the Tarsian War in the mid-24th century, was two times promoted to the rank of a subahdar. (TNG: "The Hunted")
The subhadar is likely based on the subahdar Indian infantry rank. It ranks between a jemadar and a subadar-major.
