The Star Army of Yamatai (邪馬台 の 星軍隊 Yamatai no Hoshiguntai) is the military of the Yamatai Star Empire. It performs a wide range of strategic, tactical, and humanitarian missions. The Star Army is the namesake of this website and its main role-playing group. It is commanded by Taisho Ketsurui Yui. Out-of-character it is managed by Wes.

The symbol of the Star Army of Yamatai is the Star Army Hinomaru. The Star Army's motto is “Loyalty, Strength, Wisdom.”

The Star Army of Yamatai is considered an autonomous military branch of the Yamataian imperial government. It is extremely powerful politically, with a “blank check” budget, the power to declare wars at its discretion, complete freedom from legislative oversight and regulation by the elected senate (according to Yamatai's constitution), and exclusive control over several star systems, making it a sort of “nation within a nation” that is a diplomatic entity in its own right, often making first contact and defining the empire's borders far before the civilian government does. A significant portion of the population (and the Senate of Yamatai) consists of military veterans.

The mission of the Star Army of Yamatai is to ensure the continued survival of the Star Army of Yamatai, Yamatai Star Empire, and its people and to combat enemies of Yamatai by…

• Promoting soldier learning and using wisdom to make smart, logical, and efficient decisions
• When fighting is required, fight with the utmost effectiveness
• Providing assistance to friendly peoples and forces in need

The Star Army of Yamatai primarily is based in the SARPiverse where it operates in and around the territory of the Yamatai Star Empire, excluding the space of other recognized sovereign nations. Its reach extends far beyond the YSE's actual borders. In addition, the Star Army has used Transuniversal Teleportation Drive technology to visit and conduct operations in other universes (other websites) such as Ayenee, Python Fleet RPG, Ad Infinitum, and the NationStates forums.

The Star Army of Yamatai was established in YE 22¹⁾ under the name “Grand Star Army” as a replacement for the remains of the Uesureyan Star Empire's Army Of Uesureya and UE Spacy, and the Armies of the Precious Sword, which were the private military of Emperor Ketsurui Uesu.

In YE 28, the Yamatai Space Self-Defence Force merged into the Star Army of Yamatai and the “Grand Star Army” name was changed to “Star Army of Yamatai” as part of the Military Centralization Act of YE 28.

The Star Army was later enshrined in the The Constitution of Yamatai Star Empire in YE 34.

The Star Army was a direct combatant in the following wars:

1. Chaos Hive War (YE 21, Ayenee universe) as the Army Of Uesureya
2. Fourth Elysian War (YE 23-YE 25) as the Grand Star Army
3. Second Draconian War (YE 24), Star Army universe & Ayenee universe) as the Grand Star Army
4. First Mishhuvurthyar War (YE 26-YE 30) as the Grand Star Army (until YE 28 when it became the Star Army of Yamatai)
5. Second Mishhuvurthyar War (YE 31-YE 34)

All of these wars have resulted in a victory for the Star Army of Yamatai.

The Star Army is currently fighting in the following wars:

1. Kuvexian War (YE 38-present)

This section contains other significant military conflicts or events in which the Star Army of Yamatai was involved:

The Star Army of Yamatai contains over a dozen uniquely configured fleets and several dozen organizations that perform functions such as intelligence gathering, personnel management, and logistics.

Note: some of the information in this section is a secret in the roleplay. Consult Wes for guidance.

The Star Army has ten regular fleets, two long-range expeditionary fleets, and a collection of small, temporary task forces. The space fleet is sometimes called the uchuugun 宇宙軍 (Space Army).

The Star Army also maintains a small number of decommissioned ships in the Star Army Museum.

The Star Army maintains a standing army of several million soldiers.

For detailed information, see Star Army Rikugun.

The Star Army maintains an extensive collection of support facilities throughout Yamataian space, and has exclusive control over entire planets and star systems, such as the “Nekovalkyrja homeworld” of Nataria.

Most Star Army soldiers are either volunteers from the many species of the Yamatai Star Empire, or they are mass-produced soldiers such as the synthetic military species Nekovalkyrja. There are also AI soldiers with robotic bodies. The standard term of enlistment for all species is 3 years.
