Imperial Akitsukunese Army

The Imperial Akitsukunese Army (IAA) (大秋津帝國陸軍, Dai-Akitsu Teikoku Rikugun), literally "Army of the Greater Akitsu Empire", is the largest branch of the Imperial Armed Forces and that performs land-based military operations. It is one of the six service branches of Akitsukuni represented on the Imperial Military High Council. Akitsukuni did not have a unified military force for several centuries until the establishment of the Imperial Navy in 1557. Almost 200 years later, a rebellion in 1751 by three of the seven samurai noble families against the Imperial Court was crushed by the armies of the other five houses, highlighting the need for the Emperor to lead an armed force that was mainly loyal to the Imperial Court. The Imperial Army was thus established from the armies of the five loyal noble families in 1752.

The Imperial Army is controlled by the Imperial Akitsukunese Army General Staff Office and the Ministry of Defence, both of which are nominally subordinate to the Empress of Akitsukuni as supreme commander of the military. The Imperial Army is headed by a chief military officer, the Chief of Staff of the Army who is also a member of the Imperial Military High Council. In the fiscal year 2011, the reported strengths for the Imperial Army was 279,834 active-duty soldiers and 401,876 reserve troops, with a combined-strength force of 681,710.

Imperial Army Ground Force
The Imperial Army Ground Force forms the bulk of the Imperial Army. Its primary responsiilities are the protection of the state borders, combat on land, the security of occupied territories, and the defeat of enemy troops. The Ground Forces must be able to achieve these goals both in nuclear war and non-nuclear war, especially without the use of weapons of mass destruction. Furthermore, they must be capable of protecting the national interests of Akitsukuni within the framework of its international obligations.
