Tagmatarchis, in more archaic context transliterated as Tagmatarches (Greek: Ταγματάρχης, abbreviated as Τχης), anglicized as Tagmatarch, is used in the Greek language[1] to mean "Major".
[2] More precisely, it means "commander of a tagma" (τάγμα).
In the modern Hellenic Army, the rank is superior to a Lokhagos (Λοχαγός, captain) and inferior to an Antisyntagmatarchis (Αντισυνταγματάρχης, Lieutenant Colonel), and held either usually by battalion (tagma) executive officers (battalions are typically commanded by Lieutenant Colonels).
In this case they are addressed as "Kyrie Ypodioikita" (Κύριε Υποδιοικητά), or simply as "Kyrie Tagmatarcha" (Κύριε Ταγματάρχα) in other cases.
