Ordnance sergeant was an enlisted rank in the U.S. Army from 1832 to 1920. The Confederate States Army also had an ordnance sergeant position during its existence. Ordnance sergeants were part of the Army's Ordnance Department and were in charge of the ordnance (weapons and ammunition) stores at a particular fort or other Army post. Often they led caretaker detachments or were the sole caretakers of ungarrisoned fortifications and other facilities. In both armies the rank insignia consisted of three inverted chevrons with a 5-pointed star above it.
