Imperial Izumese Military

The Imperial Armed Forces (帝国軍, Teikoku-gun) are the unified military forces of the Empire of Izumo. It consists of the Imperial Army, Imperial Navy and Imperial Air Force. In command of the Imperial Armed Forces is the Joint Staff Council, sometimes referred to as the Imperial Military High Command, consisting of the heads of the three main branches as well as the commanders of other military-related organisations.

Izumo operates a large and diverse modern military force of 1,025,470 personnel. It is a professional armed force as the Izumo constitution prohibits conscription of the populace. Izumo is known to be a nuclear-armed state and has several Sakuradite-based nuclear weapons in its arsenal.

Weapons of mass destruction
The Empire of Izumo has developed and possesses weapons of mass destruction, including chemical and nuclear weapons. Izumo's first nuclear test occurred in 1965 and its first hydrogen bomb test occurred in 1968. Izumo has also developed several types of chemical weapons, though these weapons have either been destroyed or are currently deactivated and stored in isolation.

Chemical weapons
Izumo has, in the past, produced mustard gas and phosgene from one facility owned by the now-defunct Izumo Heavy Chemicals Corporation. It has also had a stockpile of sarin and tabun gas, along with a potent and carcinogenic defoliant known as Rurushu-12. These weapons were mostly stored in the Matsuyama Mountain Bunker Complex, and have since been destroyed or are in deep storage, although limited amounts of a modified version of Rurushu-12 are used to clear the dense forests of the tropical Colonial Provinces.

At present, the only chemical weapon the Imperial Military uses is tear gas.

Nuclear weapons
The Izumo nuclear weapons program was begun in 1840 after the Narita Colonial War. This was intended to deter foreign nations from interfering with Izumo activities around the world. Two uranium enriching plants were built alongside the rest of Izumo nuclear power network in the 1840s, and the first nuclear weapon, the H-0 nuclear device, was detonated in 1848.

Izumo is known to possess the ability to manufacture and deploy nuclear weapons, with three classes of hydrogen fusion thermonuclear weapons in active service and a supposed fourth class also in existence. These are designated as the H-1 through H-3 nuclear weapons. Izumo has at least 250 nuclear warheads at present. The H-1 is a strategic nuclear weapon with a high yield. The H-2 is also a strategic nuclear weapon with a higher yield and the capability to be installed as a MIRV. The H-3 is a tactical nuclear weapon.

Izumo has a strategic launch capability consisting of MSI-23 ICBMs, MSI-25 MRBMs, MSI-22 SRBMs and Amaterasu-III tactical short-range missiles. The Amaterasu-III is capable of launching from transporter erector launcher vehicles on the battlefield.
