The Arakan Army, officially the Arakha Army is an ethnic armed organisation based in Rakhine State (Arakan). Founded on 10 April 2009, the AA is the military wing of the United League of Arakan (ULA). It is currently led by Commander-in-Chief Major General Twan Mrat Naing and vice deputy commander-in-chief Brigadier General Nyo Twan Awng. The Arakan Army states that the objective of its armed revolution is to restore the sovereignty of the Arakan people. In a February 2024 interview, Twan Mrat Naing claimed that the AA had grown to at least 38,000 troops. Anthony Davis, an expert of military and security, rejected this claim and estimated that it has at least 15,000 troops in Chin State and Rakhine State, in addition to around 1500 in Kachin State and Shan State. In the early 2010s, the Arakan Army fought alongside the Kachin Independence Army (KIA) against the Tatmadaw in the Kachin conflict. Following the 2016 outbreak of conflict in Rakhine state, AA became more heavily involved in the Arakan region. In 2019, AA would launch attacks on state security forces and the Myanmar Army would respond heightening clashes. The AA reached a ceasefire in late 2020 after eroding the central government's control in northern Rakhine. The power vacuum would be filled by the AA over the next 18 months with state-building efforts, like their COVID-19 vaccine rollouts.

Rakhine State, formerly known as Arakan State, is a state in Myanmar (Burma). Situated on the western coast, it is bordered by Chin State to the north, Magway Region, Bago Region and Ayeyarwady Region to the east, the Bay of Bengal to the west and the Chittagong Division of Bangladesh to the northwest. It is located approximately between latitudes 17°30' north and 21°30' north and longitudes 92°10' east and 94°50' east. The Arakan Mountains or Rakhine Yoma separated Rakhine State from central Burma from North to South. Off the coast of Rakhine State there are some fairly large islands such as Ramree, Cheduba and Myingun. Rakhine State has an area of 36,762 square kilometres (14,194 sq mi) and its capital is Sittwe.
