The Thyllanorian military refers to the standing forces that make up the military representation of the Lord Paramouncy of Thyllanor, which includes the Thyllanorian Navy and the Thyllanorian Army, with both having their respective sub-groups, all of which are included in the Thyllanorian military as a whole. Facing major reformation following the Dragomyr invasion of Andoras, Thyllanorian military ranks were loosely defined before then, but as a Lord Paramouncy they have been outlined and established, and most have remained unchanged since the invasion.
