Moira_(military)
Moira (Greek: μοῖρα, pronounced míra, plural μοῖραι) is a Greek term for a military formation. Etymologically, it is derived from the roots *μερ- and *μορ-, which mean "to part". Moira therefore means "a part, a division", and is cognate with the similar term meros. In the Byzantine period, it was used to denote brigade or division-sized commands, while in the modern Greek military, it is used by some branches to designate battalion-sized units.
