Major is a commissioned officer rank of the Templar Marine Corps and the Twilight Trooper Corps, equal in rank to the Lieutenant Commander in the Templar Navy. A Major typically commands a vast Battalion, normally around 500 troops or two companies plus all their equipment. on occasion a Major would command a small contingent of tanks in addition to their normal troops.
On rare occasions Gurei Deshis would be given this rank, if they were exceptionally skilled and experienced. And in the unusual case of a Gin Deshi being assigned this rank it was because they, while having the experience to be promoted to Gin Deshi in the Templars lacked the experience to be a Lieutenant Colonel or higher in the Military.
