The Royal Manticoran Navy (TRMN) is not only made up of a Navy element, but also incorporates eight other distinct components. These 'branches' are the Royal Manticoran Marine Corps, the Royal Manticoran Army, the Grayson Space Navy, the Imperial Andermani Navy, the Republic of Haven Navy, the Civilian Corps, the Royal Manticoran Astro Control Service, the Royal Manticoran Merchant Marine, and the Sphinx Forestry Service.

Each branch has its own command structure, uniforms, awards, and identity. Theses groups all work in tandem to bring the Honorverse together and alive.
