Yamatai Mainland Ground Defence Force

The Yamatai Mainland Ground Defence Force (YMGDF) is the land warfare branch of the Yamatai Mainland Defence Force. Headquartered at the Joint Defence Command Complex in Eito, which is located adjacent to the Yamataian embassy. The MGDF makes up the bulk of Yamataian troops in Chisei under the auspices of the Treaty of Mutual Defensive Cooperation, which allows Yamatai to station forces in Chisei with the purpose of "deterring and defending against foreign aggression".

The MGDF consists of about 46,500 soldiers and includes the Yamatai Imperial Army's Fourth Army Group and 410 Special Forces Brigade, and the SNLF's 21st Naval Infantry Regiment. The MGDF paticipates actively with the Chiseian Royal Army in bilateral training exercises and the development of bilateral plans. It serves as a forward stationed joint Army and SNLF command and control headquarters; supports regional security cooperation activities with the Chiseian Royal Army for the purpose of contributing to the security of Chisei and maintenance of peace and security in Central Escar; provides communities of excellence and installation operations that support Soldiers, Civilians, and their Families.

Along with the rest of the YMDF, the MGDF was officially founded in 1992. Yamataian forces began deploying to Chisei in 1980 with the purpose of bolstering Chiseian defence against Arshavat, and the YMDF was created to better coordinate local forces and increase synergy with the Chiseian Royal Army. As the largest and most visible component or the YMDF, the MGDF has received both positive and negative reception amongst the Chiseian and Yamataian public. The YMGDF is deployed in eastern Chisei, along defence lines designed to block a land invasion from Kuiju.

As per leaked documents pertaining to Operations Plan: RED AUTUMN RAIN, released by whistleblower in 2014, in the event of a Arshavati invasion of Chisei from Kuiju the MGDF is designated as the vanguard force of the HECO land counterattack.

Organisation
The Mainland Ground Defence Force is considered the equivalent of an Area Army in the organisation of the Imperial Army. It has only one subordinate Army, the 23rd, as well as several support units. The MGDF also includes the SNLF 21st Naval Infantry Kogekitai, the only case in the entire Yamataian military where a Navy unit is subordinated to an Army command.
